- Get to know the unique properties of quantum computers and the obstacles that have prevented this theoretical technology from becoming a reality.
--
Quantum computers could eventually outstrip the computational limits of classical computers. They rely on the behavior of atomic and subatomic particles, whose quantum states are incredibly fragile and easily destroyed- which is why this technology remains largely theoretical. How would quantum computers work, and are they really possible? Chiara Decaroli investigates.

I’ve never concentrated so hard and I still have no idea what just happened
Ditto
It was not a good explanation, just a lot of technical details.
Sameee
yeah, that's how quantum computer works.
As others have said, it really wasn't explained well. Yes, it's an extremely difficult subject but there is always a simple way to explain even difficult concepts to grasp the very basic key points.
My quantum states:
Think I get it

I was giving out helpful links, but it won't allow me to do that now, so I made playlists.
Check my youtube channel by right clicking on my avatar / picture icon to the left of this comment, click "open in a new tab", find the subscribed youtube channel called Technology Research with the playlists, find the playlists and click on "created playlists", I think some of them are hidden. And then click on the title / text of each playlist, not on the pictures. I would send a link, but youtube is being toxic I think, because when I log out and come back to the same videos, my comments with links aren't there, but when I log back in, they are there. Nothing like talking to yourself when trying to be positive and interested, and just trying to share the info. Please check out all the videos under each playlist from top to bottom in that order, and please check out all the playlists, and share.
It look only like dot and a line but those number if in future can be super handle everything in process, Man this is more than revolutionary there will be a group of people that will try use it to predict everything for future needs and everything (I wouldn't be surprise if there are tents outside of our house with a magic ball they call). Damn, but they say don't trust numbers 😞 *shrug*
This video legit made me feel like a child again. A person trying their darn best at explaining something as simply as possible and it is still flying over my head.
something about that really loose feeling of understanding something, and then you ask one question and everything you understand just stops making sense.
Few minutes of watching and trying to understand the video and im starting to sound like a minecraft villager.
Hmmmm?

So I'm bipolar and im complicated, does that mean im a quantum computer? Hehe
You _could_ say that your unsuredness comes from being overly sure of 2 contradictory states simultaneously, but I guess I'm kinda being pedantic.
You might like Bohm & Penrose's conception of the quantum mind though as it takes your joke and applies it as a hypothetical explanation for consciousness.
I was in a superposition between understanding and not understanding this until i watched this video
Lmaooo
Ted: Explains it in detail
Me: huh?????
yeah, in detail...
They didn't explain it well
HUH?????????????????????????????????????????????????
I would be lucky if I lived long enough to even see a Quantum laptop

Theoretically, the quantum state of matter at that scale could transfer information faster than light, so lag would be virtually nonexistent.
So a qubit is basically what I mean while saying.

Quantum computing makes as much sense to me as a camel in Antarctica. This video helped increase my comprehension to the point where it makes as much sense to me as a seawater turtle swimming off the coast of Bora Bora. And believe me, that's a good thing
Camel in Antarctica makes a surprising amount of sense.
Where am I!?!.... Did I just switch universes..😶😶
There is a theory though that says camels have actually originated and evolved in frozen landscapes. Just saying.
@smol bean Exactly! Camels were never meant to live in deserts.

"If quantum mechanics hasn't profoundly shocked you you haven't understood it yet "best line ever in field of quantum mechanics
I'll add my own quote to that.
"If Bohrs view on the measurement problem haven't profoundly confused you yet than you haven't read his response to the EPR paper."
A quantum computer? Cool, I want one!

Quantum computers are going to be great!! Hope i will be one of those who would work its computation. Such videos motivates me a lot !! Thank you #TED-Ed
making an assembler or heck even a programming language would probably be brainfucking, since you have to start all over from the ground, atleast thats what i think
Amazing video, your animations are amazing!
Actually it's annoying animation , not a Ted style at all.
Hassaan Abdalla Ted Ed always has different styles, maybe your not an artist but artists never have the same style
It's not about a specific style , but about a quality style.
A talking character like that is so boring, and the animation made the video less interesting , I've seen most of Ted videos , this is not the quality style of them.
At 0:12 huge content to animate the "artist" just made a talking character , can't u see how boring it is?
Congratulations..you got a heart
I've been following the progress of quantum 💻🖥 for a few years now. Fascinating stuff.
BuddyL You have an iPhone, right?

Hi ted-ed
Nicely explained about quantum computers...
Now i have got some idea..
Great animation...
Thanks for the video ted-ed...🙏👍😊
One of the best basic explanations I've observed so far. Thank you!
Wow ginius
I would really like a 'further reading list' under most of your videos tbh.

@@TEDEd thanks so much :)
When physics is your computer.
How much is this computer again.
It will took 50 years for quantum computers get consumer market (around $1000), same like what have Steve Jobs does in 1976
probably costs more than all my possesions
Physics
costs ~ 500 000 $ right now
About $150,000 to build your own if you know what you're doing. This is the simplest kind though
You know it will be a complicated topic when you heard the word "Quantum"
These videos really throw my brain for a loop...... and I love it!
Schools should use Ted Ed to teach more often
thanks for clearing my confusion about superposition
My reward best reward:watching your detailed +AWSOME animation
Excellent explanation, very clear, you need to understand the basic concept of computers in order to understand this video.
I especially like the part where this video never got around to talking about the high-stakes race.
Thank you for getting things right.
I was so god damn tired of all inaccuracies, spread by pseudo-educational channels.
As always love the animation nd easy explanation.
With this video I learned that the quantum computer can have certain advantages over the classic computer due to its features and composition but at this moment it is still necessary to work for this type of computer to reach its expected level, I learned how ions can be quite useful but for other side it can be difficult to mantain its accuracy, with the circuits is easier to obtain greater accuracy but it has a shorter lifespan, with all this I learned that there are several ways to do something because each thing has to I found the idea of the video quite interesting and for that reason I liked watching it.
I love it when someone is animated talking in the Video. I wish there are more of these
Your videos have taught me more than school
the animation makes everything interesting!!!!
I lost it at 3:16 "The laser could input the question..."
Omll so true
I love Ted-Ed ! ♥️
Had no idea it was so simple, thanks!
*I hope these things won't backfire when computers are smarter than us.*
@Sticks Studios which is why, it is general AI that is dangerous.
general AI should be able to do everything, which hasn't been achieved yet
@Sticks Studios which is what we will do too
The race will never end because basically you can make quantum computer work and not make it work at the same time.
Hehe... The old quantum joke.
Only when you're not looking though.
So, what you're suggesting is Schrödinger's PC? 😉
This is super fascinating.
Amazing work. 😃
Mom remember you told me you will buy me a new gaming PC...
fist ever video I watched that explains how qbits are physically implemented. Can you please make a follow-up video to explain how the qbits are made to get entangled with each other during the quantum computation? Some more details on the photon-based observation will also be great.
great clip!
But the important question is
(DOES IT HAVE A HEADPHONE JACK)!!!
lol
Super well done on this video! As a former ion trap quantum computing scientist this is the first video that I've seen that makes sense of the field without getting so complex it's incomprehensible. Also, Ions rule, JJs drool (but I'm a little biased on that, hehe)
thank you!!! I am very glad you liked it!
I find this interesting for two reason :
1.) what would happen if I use a quantum computer as a gaming computer?
2.) Time to dive into the dark web, or was is the deep web? Let’s just do both
Also the Mariana's web, which people said can only be accessible by using a quantum computer.
Dark web is below the deep web. they are not the same.
Great video
This is the most fascinating thing I've ever seen. Basically, Superconducting Circuits are like Intel CPUs, where they have faster IPCs than Trapped Ions right now, but will run into the limit of architecture. Meanwhile Trapped Ions are like AMD CPUs before Ryzen came out, where they lose to Superconducting Circuits IPC-wise, but can theoretically make up for it by continuously adding more and more cores aka Ion Traps.
You really make great videos
Woah I’m surprisingly early for a ted Ed vid
Everyday we learn, thanks
"But in spite of all these obstacles, we've already succeeded at making computations in a realm we can't enter or even observe." That was as inspired as it was poetic.

Super job, narator.
These videos are so informative, and yet my brain wants to explode trying to comprehend anything relating to quantum theory.
So cool!
Currently working on quantum computing
First of all
Amazing video
I cannot agree more on the quote by Niels Bohr
One thing I would add is optical quantum computing is the most promising one of all
What are some good resources on quantum computers?

Big fan of ted ed
Hey ted-Ed, awesome video! I’m really into philosophy and I was wondering if you could make “Why should you read?” Episodes on Thus spoke Zarathustra by Nietzsche and The stranger by Albert Camus. Most people at my school don’t know much about philosophy and I want to share my passion of philosophy with them. I think your videos could explain philosophy for them and open their eyes to the beauty of philosophy! (Going into 8th grade this fall). Hopefully you consider my ideas! Thanks!
Why not use magnets to correct any frequincy variations while using magnictic sound waves to hold the ions in a better structure?
I understand perfectly now.
It is full of knowledge
Her voice is super relaxing for some reason.
first video who actually explained what a qubit is and properly said what is a superposition, and not the popular hand waving "is 1 and 0 at the same time!" who doesn't make sense and make it worse to understand
This vastly undersells the differences between quantum and classical computing. It makes it sound like all we'd need to do with classical computers is add a few more bits.
Me : Hey quantum computer , tell me 2x2 .
QC : it's 4 . No it's 2 . No 6 . No it's 8 .

Would different color laser work for more computing power with percussion?

Great voice!
You should do a video on Australian Rules Football (AFL) it's Australia's national sport and we're crazy about it over here but its almost unheard of overseas. The AFL Grand Final is the highest attended club championship event in the world including the super bowl and the players can run upwards of 20kms per game compared to soccer player's 13km. The game is fascinating and unlike any other sport around the world and it's so crazy that its such an institution in Australia but even American sports fanatics have rarely heard of it.
Check out the video called "What is AFL? Aussie Rules Explained"
When you say you've already made computations have you actually seen comprehensible results like being able to type 2 + 2 and have the quantum computer answer with 4?
WHO IN THE WORLD DISLIKES THIS VIDEO ???
Nice
what i don't get is how do you get any useful information out of a qubit if its impossible to read without destroying the data? How do you know what amount/frequency of photon corresponds to what part of the qubit if you can't read the qubit to compare?
Nice , IBM are working to produce one and it has alot of pure gold in it!
I UNDERSTOOD EVERYTHING!!!!
maybe??

Iddris sandu taught me about Quantum numbers , it’s interesting.
This is the beat channel on you tube
This might be the 100th video I have watched about quantum computers and still have no idea how they work.
This is giving me math exam flashbacks...
At 3:44 they say that the only factors of 15 are 3,and 5 while they are 1,3,5,and 15
Yes but 1 and 15 are trivial...
Imagine the time when our computers now would be called "classical computers" as being looked as a vintage and a normal laptop or smartphone is a quantum computer..
Cool
So by pure estimation
how many times faster does the quantum computer vs classical computer?
considering ions, laser and qubit vs ram, processor and vcard.
the answer?
Yes
As much as i understood the Q-Bit, the explaination is reasonable simplified, but make the quantum-mechanics really complicated and obscure to understand, if you want to dig deeper.
Maybe i'm writing complete sh*t, but i'd explain it this way:
A Q-Bit has 3-axis which can be positioned with the Nort-Pole (Electromagnetic field like the earth has) up or down.
The Super-Position describes, when the Q-Bit is somewhere between these points.
Because it's not a finite number, the North-pole can be 2/3 to the top, so basicly be 66,6666666666-> % Upwards showing.
Tecnically in both the x-y Axis and the x-z Axis, but we can only measure the polarity on up or downside.
The interesting part, since the position of the axis is somewhere between 1 and 0 (up or down showing), and you can make an infinitely-small fractal of the number "1", you can basicly calculate with an *potential of infinite-accuracy* (depending on the accuracy on the input data)
The problem: we can only point the QBits accurately up or down (absolute values) or use some (really complicated) operations to make them point as a bigger fractal. so inputing Data is limited to an *finite* amount of accuracy.
The calcucation however can be done with infinite accuracy since the QBits interact by quantum-mechanically linking them together. (Basicly Physics calculate a 3D-Value, with *as-fast-as-possible* speed).
Problem two: Reading the values, since our measurements can only tell if a QBit is with it's northpole upwards or downwards.
(QBits are really tiny after all), so a QBit 2/3 upwards, will be read 2/3 of the time (or 66,666 %) as a *true* and 1/3 of the time as *false* ... So you basicly recalculate your programm so often, you get by statistics the position of the QBit (as many itterations, the more accurate your reading).
So the Supoer-Position is basicly only a state, which we can't create (only fith a finite amount of accuracy, which defeats the purpose), and we can only read one Value, which Statistically Chances is the only way to tell us, the actual value *approximately*!
*TL;DR* The Super-Position is the State in which a Value is stored with an infinite amount of Accuracy, which we can't create by our own, since tecnology can only calculate with finite numbers.
What about some kind of dark mirror
Just like computers 80 years ago big and expensive.. just wait next 60 years quantum computers will embed on your smartwatch, it will!
Wish I could live that long to witness such a miracle haha
