‼ Sorry guys, I messed up. I meant quantum INTERFERENCE, not inference. It was a long day 😅
Please make one about NVIDIA vs Google A.I-GPU architecture! And no! just architecture, size, etc... will not accomplish data gardering necessary, and google has tons of e-book's GPT will never have along with conversations and videos...
no worries, we understood that you meant interference
Please work of pronouncing the T in InTerference, it sounds like you are saying inference which is more a task the CPU/GPT might be used for.
dw you're fine, ty for lettings ppl know
The neuron is thousands of times bigger, yet the brain has more capacity than any computer, proving that it's not size that matters, but architecture.
The molecular structure in the center of their figures is a porphyrin ring structure. It has lots of interesting features and crops up all over nature when moving electrons around. It's been a candidate for cool logic and transistor designs for decades. For example in [Barker, J.R., 1987. Prospects for molecular electronics. Microelectronics International, 4(3), pp.19-24 , doi:10.1108/eb044287 ] Figure 5 reports a NAND gate where the central structure is the same as here but it has a much larger overall structure for doing things optically. (Hope that is interesting!)
you are amazing
Yup, put a divalant atom in the middle and you can tune it to all sorts of stuff ranging from photocatalysts to energy harvesting to quantum phase modulators like described as single atom transistors.
So, what is new in this latest proposal then?
From a theoretical point of view metal complex compounds are interesting becauce we easy can change the electron density in the center ion by variations in the ligand. So a lot of research was done with organic semiconductors. I worked in solar vell research and there it has a big advantage over silicon as it has a highter absorbtion coeficient for light.
@@koka3243 It is a step forward from theory to application.
I'm an old chip designer myself , worked at Intel in the old days - then S3 ... I thought your talk was excellent The idea can be applied to other materials and higher temperatures. It's quite profound.
I worked on the ill-fated Chipgraph, and then the apparently-ill-fated BlockStation
You do an incredible job of making complex concepts simple to understand. "If you can't explain it simply, you don't understand it well enough." - Albert Einstein
There is also the other side of the coin minted by Einstein: “Everything should be as simple as it can be, but not simpler” - a scientist’s defense of art and knowledge - of lightness, completeness and accuracy.
I've made zinc porphyrins for a year during my master thesis!! 😃😃
(it was for a completely different reason though, it was for renewable energy)
Zinc porphyrins are actually quite easy to find commercially or synthesize, and the molecule there presented doesn't look too different from some of the ones I worked with. I could see it scaled up.
Porphyrins are organometallic structures found in biology. The ring holds a metal ion in its center. In animals, the metal atom is iron and the porphyrin is at the heart of hemoglobin in blood. In plants, the metal atom is magnesium and the molecule is chlorophyl, which captures light energy in photosynthesis. In your video, the molecule between source and drain is a porphyrin where the metal is zinc. I don’t know what characteristics of this porphyrin ring structure makes it a good FET channel.
I am guessing, this is a natural single-electron transistor (SET) - single electrons can jump on-off that island in the center of the molecule. But why cool it? It should work at room temperatures as well, given the large Coulomb gap (in the energy spectrum) at this size. By cooling you get the so-called single impurity Kondo model that describes the system, with spin replaced by charge. And you do get quantum description. But it should work in the classical regime as well. Too lazy to read the original article, though, will just wait for someone to explain this on YT)
@@koka3243 I think she mentioned somewhere in the video that the problem wasn't the porphyrin, but the graphene at the ends.
Apart from the issues with temperature of the source and drain graphene, I wonder if the other major issue is scaling processor interconnects down which may also suffer from quantum tunnelling effects at particular scales/current to connect to the transistors - to then be connected to at the classical computer layer (MB IC, RAM, I/O etc). Likely this will be a long way off from commercialisation, but this research could lay the foundations to solve the other problems for the implementation of transistors designed at this scale. I do know there was some work in the quantum computing space for generating and controlling single electrons, so certainly the techniques are actively being developed - but if super-low temperatures are required for operation (electron control/source & drain stability), it makes the plausibility of these systems for generic computing unlikely.
To those complaining regarding pronunciation - English is clearly not her first language - stop obsessing and just listen to the content without adding comment. It's perfectly understandable and very interesting.
Bravo!
*FAR from perfectly understandable.
Yes, very interesting but too cringey n 4 that reason I'm out at ~2:00.
@@ralph3333i don't know why a person that is talking about physics is cringey
As a non native English speaker I find her hard to understand, kind of distracting even with subtitles. Great content and explanations, per se.
I think how some people pointed out the pronunciation was fine because knowing that she meant interference, not inference is a distinction we need to fully understand what the presenter intended. They are similar only in how they are spelled and sound. Inference is a conclusion or deduction based upon evidence, particularly indirect evidence. Interference is intervening in a situation where it is not necessary or inserting oneself in a situation where one is not wanted, meddling. Interference in this video is the waves interfering with/cancelling each other out.
I worked in the semiconductor industry working in plant automation and data collection for close to 30 years. The technology was astonishing back then...it is mind blowing now! I enjoy your channel immensely! 😊
Back in 1987 or so, I worked at a place that was using a process called Molecular Beam Epitaxy, MBE.
They were using it to build GaAs transistors directly on a ceramic substrate.
For the time, very fast, I didn't realize how fast until I overheard some people saying that they were getting a 9db gain @ 60 ghz! I asked where they found a scope that could read a 60ghz signal. They told me they didn't, that they had to extrapolate from sub harmonics. Saw some strange stuff there! Not aliens or anything, just people pushing boundaries.
It's a fascinating idea. LIGO can measure *1/10,000 the width of a proton* using interference. Wavelengths can be far smaller than a nanometer. If we start building transistors that work at these scales, this is like putting us in the position of PCs in 1980 again in terms of Moore's Law, and we would be on the verge of a whole new paradigm in computing.
This sounds interesting.
Are you living in a Star Trek universe? This is clearly impossible.
@@tempname8263 let people dream bro
And if that then, humans in a thousand years are going to be perturbed that mores law is approaching plank length.
@@tempname8263 What exactly do you think is impossible? Computation with waves? This has in fact been thoroughly begun including useful algorithms involving matrix calculations utilized in optical computers. If you think electrons are not waves? If you think transistors have to be Newtonian physical devices? What is impossible is arguing against such a vague assertion of possibilites.
Well. You got me considering learning more about transistor and quantum tech in my free time.
She's married dude... but I feel your pain. 😄
@@CensoredByCZcams. Eh, I've been genuinely considering this stuff for a while after knowing couple of folks who keep telling me about this stuff, lol
@@CensoredByCZcams. Maybe their marriage is destructive inference?
challenge accepted haha @@CensoredByCZcams.
Always interesting stuff, especially as it’s right at the cutting edge of transistor development. Why do I enjoy your channel? Well who else can say the phrase “Let me simplify this to the most basic level” and then you start a discussion on sinusoidal constructive and destructive interference as it applies to wave/particle duality and quantum tunneling…Love it! Keep up the good work :-)
this is just amazing! i'm not from a technical background and am more of a software guy, i've always wondered what would happen after they reach the 1nm limit. It seems like we've got a long adventure ahead with our normal computers.
Super interesting, thanks! In the how it works section, I think the word is "interference", rather than "inference".
"Inference" and "interference" are very similar, but not the same word :-)
^this
wdym they are completely different in meaning
@@genres381 She sometimes says "inference" when she clearly means "interference".
@@genres381 Levenshtein thinks that they are similar :)
Fyi she has a pinned comment at the top acknowledging the oversight.
Plants do very interesting things with porphyrins. Chlorophyll is a porphyrin (as is heme, a component of haemoglobin) and chlorophyll of course enables photosynthesis in plants, without which there would be no oxygen in the world and we would all die. Take home message: 1) porphyrins are amazing 2) we must protect and preserve our plants and trees :)
Interesting enough during the synthesis a copper atom is inserted first then replaced with iron or magnesium depending on if heme or chlorophyll is being made. It is also why copper is poison to plants, if too much copper is absorbed the plants cannot properly synthesize chlorophyll.
And apparently, chlorophyll relies on an amazing quantum effect to work irs magic. I'd like to learn more about that!😮
@@user-gv4cx7vz8t I can add that copper is what gives chlorophyll its green color.
It's interesting that plants use this metal and several other metals to process photons.
It would be a misconception to say that plants use various metals to process (and I will even say calculate) electric current similar to how computers use various metals to process and calculate. It would be that computers have some plant-like behavior not the other way around. Quantum Biology and Organic Computing is perhaps the most interesting because it is thought to be 3%-100% efficient depending on what is being measured. I think technology can continue to improve so long as researchers are grounded and in touch with nature.
Most of our technology is a result of analyzing and attempting to synthesize and replicate an existing natural behavior or state.
Just spit balling here but I wonder if the right copper mixture could be developed for solar panels. Currently Silver is the metal being used in solar and as far as we know silver is the best. But silver solar panels are only like 12%- 20% efficient.
I think we have more to learn and apply from photosynthesis, thinking there will be a major leap in solar efficiency and significant production cost reduction.
If people could figure out how to mimic photosynthesis with new ideas (like as described in the video) that makes current obstacles strengths instead of the reason why it's currently impossible that would be very cool.
My apologies I possibly could have been more concise and or perhaps more accurate. Yet I wanted to present my thoughts and move on.
Enjoy 😊
You forgot to mention that plants breath CO2 in order to produce oxygen, so we should all buy big block engine cars and help feed those plants.
@@thatscrazy4487 so plants breath / absorb whatever is in the air (air is not exclusively oxygen and carbon dioxide) air earths atmosphere is mostly nitrogen, nitrogen (N2), 78.084 ; oxygen (O2), 20.946 ; argon (Ar), 0.934 ; neon (Ne), 0.0018 ; helium (He), 0.000524.
Yes it's mostly the CO2 that is used to produce oxygen. But plants take in everything and if it's good they metabolize it if it can. Trees consume and metabolize methane, nitrogen, and likely all other gasses and vapors that are in the air. I'm not an expert obviously, but I'm not an initiate ether.
The strangest thing to me is the current belief is that trees turn sunlight into sugar. I disagree completely with that theory.
I think it's more like the sunlight/ photon is being used to cook, distill, and solidify one or several elements (depending on how much of whatever the tree may or may not be deficient or genetically predisposed to need or produce) to make ingredients for making the sugar.
Sugar is a carbohydrate it's composed of carbon oxygen and hydrogen. So it's not the sunlight that is being turned into sugar. It's the sunlight being used by the tree that turns the atmospheric gasses (that trees breath from the air and absorb from the ground) into liquid and solid sugars as well as other body building components.
Capillary action in plant cellulose and various gravitational fields (mostly the moon and sun fields) are responsible for moving solids liquids and gases throughout the tree. For simplicity sake let's just say vital nutrients. The mechanisms for vital nutrients motion.
The photon is a non-additive catalyst. Consider electrolysis for a moment. When the current is turned off did the water hold and retain all the electricity that went into it? No it didn't, you can touch water that was electricity charged and be fine because it is no longer charged. The water is turned into hydrogen and oxygen by the electricity. The electricity was not turned into hydrogen or oxygen, the electricity is not stored in the water. From start to finish the electricity is a non-additive catalyst. The photon is a non-additive catalyst at all times. Light and heat convection, conduction, and radiation not adding to or taking away any matter at all but the mechanisms of elemental materials electrochemical transmutation.
For all we know photosynthesis may be entirely dependent on Nitrogen, Argon or Methane as a linchpin. Maybe the reactions and oxygen production would be impossible without hydrogen or something.
Just food for thought. Thanks for considering. Enjoy.
I love your videos. The visuals compliment your narration so i learn stuff AND find them entertaining

@@dtrueg already married? Then I'll stop buttering her up. Unless....if she is BI like me AND her progressive husband doesn't consider being with a woman as cheating 🥰
I’ve been absent from CZcams for a while and coming back your content. It has taken a quantum leap 😊 in production quality and presenting. I personally would like more cat tho.
The use of Graphene reminds me of the beginning of the use of Gallium Arsenide low noise microwave amplifiers. Initially to achieve the required noise spectral density the devices had to be cooled to -70 C. Eventually performance parameters were achieved at room temp some 20 years later.
When you absolutely must have it now and can't wait for 20 years of R&D to catch up, you go exotic.
Side note... Are there any "supercomputers" like the Cray anymore? With exotic sub zero cooling?
I can imagine watercooling is probably a thing simply because of the heat transport potential vs air, but I'm not aware of high end refrigeration in the supercomputing space anymore.
As far as I'm aware, the focus has been on more units of fairly mainstream-adjacent hardware with almost generic data centre practices.
The molecular structure is literally the same as hemoglobin and chlorophyll. It's not graphene in that arrangement.
The use of Graphene reminds me of USD billions in snakeoil and false promises.
You managed to explain realy complex idea in a way that even non technical person, such as i am, could follow up and understand your exitement about this new breakthrough.
You are doing a great job.
Thank you again for another interesting video. I always learn something new when I watch your videos.
This is perfect for super small Analog processors. Imagine the gate voltage controlling the superposition/probability amount of the quantum tunneling on the source. Even if you can’t measure the current flowing to the drain, you know based Schrödinger calculations the expected current out on the drain compared to your variable gate voltage and constant source voltage. Mapping this over and over again can allow you to make a resolution like digital waves.
Funny, I was just thinking of Digital waves
Thanks for the great overview! As someone completely outside of this field, it is extremely helpful to have this kind of explanation. Always much appreciated!
Information rich. A complex topic very clearly explained with great graphics. And also links to source paper. Very professional. Excellent.
There's been a fair amount of study on computational molecules. The linked article mentions zinc-porphyrin as molecular transistor is what they used. You can see the 2D ball-and-stick representation in the video at 15:23 for example.
I used to work in this space and I can tell you:
The fact we have no ability to use much of our silicon manufacturing technology means this tech could be more than a decade from practical implementation.
This is not just one exotic material, but two or possibly several to get this type of device working.
The graphene interconnect is actually more annoying to fabricate than the transistor, because you can functionalize the higher surface energy edges, but making a large and highly ordered graphene lattice is hard. CVD and Osborne ripening can only get us so far it seems.
Practical implementation would only be in data centers
The need for cryogenic temperatures to make this work is also a major challenge. That means for a while, this will not be accessible to consumer devices. This tech will languish the same way standard quantum computer have for the last several years.
This tech may not help us *quite* keep up with Moore's law, but we will use it or a permutation of it eventually.
Thanks Anastasi, for another very clear and interesting deep dive into the complex nature of chip design !!!
What an elegant concept to turn the interference pattern of interacting orbitals in a single molecule into a working transistor. Let's see how it goes... 👌✨
Interesting as always!
Regarding audio: there's some low frequency noise every now and then, for example at 14:47. (i can see the microphone physically moving, so perhaps a microphone physical isolation issue is the root cause)
A high pass filter at 120Hz would solve that
200 billion transistors on a GPU compares pretty closely with what I'd estimate to be about 900 billion transistors on every 6502 ever manufactured, combined. (I'm guessing about 200 million total 6502s were built, though that's a very rough estimate).
My favorite fantasy game: try to guess how square mm silicon need for a c64 computer or my first 286 pc.....
I think a qfn32 package will be enough....
@@gyubear I'm currently designing (for my own solace, maybe I'll end up publishing it as a didactic example) a very simple computer, with no CPU or ALU but able (in theory) of computing maybe 200,000 8 bits × 8 bits multiplications per second, and with special features such as every microinstruction being tagged one of four execution modes when used: unconditional execution, execute if X flag, execute unless X, or Breakpoint (to debug instructions' microcode or the hardware).
Amazing magical tech priestess :) Thank you for another very educational video. You explain things very well, a 500-level class packed into 16 minutes.
Someone mentioned how Plants use Quantum Effects but weirdly theat small bird the Robin has a structure in its Right Eye (not present in the Left Eye) that allows it to detect the earth's magnetic field using a Quantum Effect.
So I'm sure, with these naturally occurring real world examples, that do not require "super cooling" we can look to nature for inspiration.
Thank you for your love about electronic and way of explaining stuff.
Hello Anastasia, in 8.49: it is not the
inference but the interference that causes the problems.
Inference is meaning to bring in or to deduce.
Interference is intervening in a situation.
XLR audio cables have 1 ground and 2 signal. One of the signal conductors is 180 degrees out of phase. The receiving end flips that conductor to cancel out line noise and achieve very good SNR of the source audio signal.
Really cool, thanks, I learned a lot! Am in software but love to follow physics and chip tech breakthroughs, and this sure is a breakthrough
Your channel is so underrated. Just keep up those uploads people will catch onto how brilliant you are.
Thanks to let us in touch with these technology breackthroughs with all this working details very interesting.
"Computing with light" is not the way to go if you want really tiny devices. The wavelength of an electron depends on the energy we gave it, but for reasonable values is around 0.1nm. Visible light has a wavelength of hundreds of nm and even the deep ultraviolet that is so hard to handle is more than 13nm. The devices to handle these photons would have to be larger than these wavelength. But there are many other good reasons to switch as much of the system as possible from electrons to photons.
had a good understanding in the first half of the video, good job. the fact that they tested it in negative degrees and (relatively) low frequency is a bummer though... guess we are not getting any breakthrough anytime soon :(
very interesting video and explantation.
Before going to the end, I paused the video as I though of something, and wrote them down on paper :
scientific aren't explaining the "roles" of particles and waves (they already have difficulties to explain "roles" of each proteins in body) :
would waves may hold information about particles when the latter moves?
(I will try to explain part of my thought here)
eg: spreading a new "wave" onto a particle alter the particle's behavior and/or it's interaction with other particles (whose electrons)
in the reverse process, additional wave could make a particle to move (transferring new energy to the particle) so making this particle to move (new behavior / state).
So in the approach, new notion would come up :
wave would act as enabler as well as "information keeper" when the particles are moving, and particles would transfer some of their information (behavior, interactivity with other particles, environment, but also the notion of "weight") to the "wavelengths", and back and forth
(the particle would "only" keep information of structure - but I haven't really think of it)
this approach could also explain "dark matter" in space, and why signals can't go through and back, how some particles could pass through "walls" and reconstruct them-selves.
to simplify : No motion -> no weight (eg : stone). motion -> wavelength (information transferred / stored into wavelength with "parity process") :
when you see a stone : you can't "feel" the weight (you can just imagine it)
when you take the stone : you feel the shape (particles interaction?) and can just "guess" how heavy it is (information start being transform into waves)
if you can hold the stone and move it : you can appreciate the new weight, as you also moving the stone and your hand & stone wavelength are "sharing informations",
you can't crash the stone into your fingers/hands because you would change the particle state (quantum states) which would need much more energy and a bigger "wavelength" to hold the information, but if it cannot -> everything spread out and is broken as you have just lost the wave's information (environment for the particles, interactivity, reconstructibility, weight), but as the universe doesn't like instability, this result into expanding / collapsing process (space & time) to be stabilized as soon as possible (creating new combos for each particles/wavelength pairs).
This is crazy. What a time to be alive.
I do like the way you explain in your videos, specialy this. I have though about this more and more.
A noise-cancelling gate to prevent leakage. Brilliant!
Wave theorum and Quantum effects.
I have a bit of a leakage problem myself, maybe I can apply the same technology in my situation.
@@thatfatman6978 flex seal may be able to help
@@thatfatman6978 So whats why the other channel gets blocked every now and then, I'll explain it my doctor.
all "particles" are waves, and even bigger structures as atoms with many protons can behave as wave, or even group of particles. It is that our past knowledge about particles is only snapshot, and not reality (photons are interactions, and people forget that they are "observers")
That really is interesting. So using destructive interference to open and close gate.
She said inference, not interference.
14:29 some people who watch this video will think that shot of the Starship landing is CGI but amazingly that's real video feed.
Loved watching her excitement build up as the subject gained in complexity.
I asked my "Sopon" to explain the confusion between the English words "inference" and "interference". My Sophon stated that this is just another example of them trying to sow confusion and slow human scientific progress. "She" added that representing such concepts as Chinese ideographs makes them much clearer! 😅
Fabulous video, your explanation of why there is leakage & cancelling the leakage was simple, clear & easy to understand irrespective of the nouns used. All technologies have limits. You can only run jet engines up to the temperature limits of the materials & fermion (e.g. electrons) will not be retained by a thin walled barrier. Indeed many atomic nuclei decay when such decays are classically forbidden, but the decay fermion, alpha particles or positive or negative electrons tunnel through the classical impossible to pass barrier. The theory of this barrier penetration is well established & covers half lives from the age of the universe to fractions of a second. As you say the leakage can be switched off, but it’s slow & complicated & currently not practical. At some point we will reach the limit of electron technology & move to better ways. For example if you can store information in atomic nuclei the size scales are femto meters 1e(-15)m, or we can use photons. Thank you for the fabulously interested & well presented video that must have taken a long time to create.
This is amazing news, to consider that a transistor can be so small. I must say I'm barely an amateur electronic hobbyist, having studied the basics of semiconductors like MOSFETs and the simple 555IC timer, to make wave form generators for audio applications. But to consider even these simple circuits could be made in forms smaller than the width of an average ball point pen line, just blows me away.
I think of that fluid check valve design with no moving parts, and to consider harmonic and disharmonic frequencies used as the switching base it makes me think of how electronic devices could interface with human bio-enegetic energies of the Aura (Chi), and even biological nervous systems.
Thank you Anastasi for sharing, I love your excitement and willingness to bring these advanced developments to the general public. 😉💖✨
Who knew that the future of transistors would be so... tiny? Like, literally the size of a single molecule! I mean, I'm no expert, but I'm pretty sure that's smaller than my attention span.
Anyway, it's cool to see scientists harnessing quantum effects to create a new kind of transistor. Thanks for explaining it in a way that didn't make my head spin, Anastasia!

Tht Quantum interfere interference is not a big deal. I got what you mean. It was a small error
I was talking about computing with light back in 2006 and an ex intel phd told me it would never happen. I see quantum wave computing as entirely possible.
Your awesome!! Thanks for all the updates!
As a layman, I wonder about increasingly possible damage to such small-scale devices from free-flying cosmic particles.
I hadn't thought about interference at channel sizes and the implications. Thank you.
Wow, this is so simple, yet genius, and once you see this approach, it's so obvious, but we didn't see it before.
Instead of trying to turn on and off the gates, just let the waves cancel each other out, or add together to send a high signal.
I hope they can commercialize and scale this approach very quickly while solving energy consumption and thermal profile concerns. What with AI/AGI powering the next wave of technological innovation.
If only solid state devices worked off of hand-waving.
If im an expert? well im a seasoned youtube commenter, that makes me an expert on basically any subject.
It's impressive. Using quantum tunneling and destructive inference as an advantage to work around the transistor size limitations.
Thank, you for the different perspective on quantum interference. Instantly thought of the old cartoon "Wonder Twin Powers Activate!!" Not a favorite of mine but a memory all the same 😅
Thanks, that was quite interesting. However I thought I heard you say "inference" and I always thought waves interacting was "interference" and this confused me.
The main problems are yield, and radiation which will cause many soft errors. So it is possible to go below 28nm but the cost per transistor stays constant or rises slightly. So unless you need the space it probably not worth going below 28nm.
Fantastic! I used to be a PCB designer back in the day. I miss it. This stuff is just MIND BOGGLING!
insightful, thank you for sharing. Error correction, noise mitigation and decoherance are fixed then this could be revolutionary paradigm shift in computing .
Super interesting. Great video!

fascinating stuff as always, love your videos..
3:35: I am guessing that the process they use to create the wafer, could give you meaningful control over this process. And over the band gap. One way would to be to change the composition of the resistor itself. So that you gain access to the equation that is the band gap.
So what I am talking about, is change the composition of the wafer, so that is as a hypothetical: 6 parts silicon to ? parts something else. Just like graphene changes the equation of the band gap.
When the tech for the wafer was originally created, it probably was not made with controlling the band gap in mind. Again like the graphene.
Spraying on another layer might be an idea. So that you have the two parts of the resistor made of different materials. This could be tough though.
I have edited this a second time and still no love heart:) LOL
You are a great teacher.
Superb explanation of where we are and going with this technology. Thank you Anastsi & Cheers from Seattle !🍻
The illustration of how noise is cancelled out is exactly how a XLR microphone cable works. it reverses polarity of the noise on the cable at the end points of the cable.
The neuromorphic computing approach, I think, will solve the problem of the processor's internal frequency, which cannot be increased, without the need for smaller structural manufacturing technologies. Because our brains can perform sensory and intellectual computations at very low frequencies compared to processors with very low thermal capacity. Also, we always lithograph the logic switching gates in a planar structure. While we plan very comfortable growth in 2 planes, I think we do not think enough for connections on the 3rd axis. I think if we build a model of the brain with basic physics and chemistry, we will reach the next layer of computation needed without opening a door where sub-quantum effects will emerge.
SSDs and modern memory already employ multiple layers on the same silicon die. Toshiba uses 16 die stacked NAND chips to enable 16TB SSDs.

From what I understand, the principle of indetermination doesn't allow to know when the tunnelling occur - after the charge carriers have diffused in the gate...
Thank you for explaining how the marketing equivalent of nm was implemented... knew it was the case but didn't realize it was because gate went vertical.
Well presented. Thank you.
Definitely need to solve that temperature problem before it could be viable. Once it's been proven in one molecule though, we know what's possible, and that makes it vastly more likely that we will find a viable alternative. Let's just hope that it isn't like the search for a high-temperature superconductor...
Interesting. Are the graphene transistors always P-channel like the diagram, or can they also make N-channel graphene too (to allow complementary arrangements like CMOS styles)?

this channel should have at least 1m subs gorgeous model anouncer great topics pro efiting i dunno why is there only 176k well dont worry i'm sure it will grow much bigger ... eventually
very nice talk about a high end subject

Multiple Multiplexed Clock Timing Signals should be used to shorten the timing cycles for clock signals into registers in parallel fashion. The machines cycle time could be shortened for
faster compute speed. Various schemas could be considered with a variable word length paradigm.
I was just thinking about optical circuits ... and how to make an effective "transistor" in optical circuit paths, and I thought about .... 180 degree polarization of a secondary beam path that can be allowed to pass through a lane or not , and every time it aligns with an existing optical path, the polarized (180 degrees) beam would negate it. How fast can a beam path be opened or closed, turned on or off? it seems to me that each "transistor" would have to be able to activate or deactivate the secondary beam, but in order to ensure that the 2 beams (more or less) perfectly deconstructively interact, they have to be in sync, which becomes really challenging when you're turning light sources on and off based on desired outcomes / etc... is there a better solution?
but then again, having a secondary beam source inside each transistor seems like the only way to do it fast enough to maintain greater than 1Ghz switching speeds, and that's kind of important for computational purposes...
