This explanation, like every one I have read or watched, really doesn't explain how QCs will work. It talks about qbits, entanglement, and such, but how do these things contribute to a computed answer? This is like explaining a classical computer by saying it consists of binary digits and then stopping the explanation right there. I don't care how may qbits some experimental computer has. Tell me HOW it uses those qbits to do useful computation. Are there quantum logic gates for instance? Haven't heard any QC explanation tackle that question.
Apparently they can't do useful computations, and are very error prone. My question is like yours, and I want to know IF any QC even works, even a little bit? Is there a working QC? If there was, it would imply the many worlds theory is a universal fact. That would change the way we understand the world and the nature of the universe. Quantum computers will likely never achieve anything useful, in my opinion, because I think our understanding of quantum mechanics is severely flawed. But, if QCs manage to work, then, that means superposition really is possible, and the "magic" would become a real science. It's interesting to see how this idea is being explored, yet I have little faith in the QC's ability to achieve any problem-solving whatsoever.
@@Cicada3773 Quantum mechanics is actually the best tested framework in all of physics. It has no more flaws than any other scientific models: point being, it is incomplete (mostly with respect to gravity). That modeling of it can be difficult, but it is extremely solid. Not sure of your 'superposition/possible" words. I suspect you do not understand the term. Superposition is a very real phenomena that long predates any applications in computing. See anything by Dirac, Feynman, etc...Yes, of course, QCs are error prone. Welcome to computing. Error correction and fault tolerance are critical developmental segments in QC (entangling atoms, ions, photons is tricky) - but classical computing and IC logic have always wrestled with the same challenges - only now on a smaller scale. The end computation still occurs on a chip, btw. Classical computing has had a generation of scale and ample years of commercialization to work it out. Early classical computers could not much either. Quantum computers can certainly do computations (you can build quantum algorithms on IBM's platform in their public cloud right now) - but the real age of QC will come when they scale them to do things classical computers cannot. Likely in 5+ years. (~ a physicist with a degree in quantum mechanics)
Yes - there are quantum logic (Boolean, for example) gates that are used to abstract quantum circuit logic that are composed into focused quantum algorithms. The quantum algorithms are built for certain general computational tasks (not much difference than, say, how certain neural networks in machine/deep learning are better at some tasks vs others). There are countless videos on YT on your questions.
@@jonesyjones8026 I completely believe that there is a God, and in the light of experience in quantum physics, I know that there is a God who is almighty, He breaks all the laws of physics.

This is severely underrated channel I've ever seen with the greatest potential........ That could be solvable with some great creative thumbnails tho..... I think....
Same here. Even if you tell it the answer, how do you know when the answer is achieved if the only way to collapse the system is observe it? Also, iiuc, “good” encryption algorithms (since breaking encryption is often cited as a quantum use case), even when you get the keys right, you aren’t presented with a light bulb that says “unlocked!”… you just get indecipherable garbage on the other side, which again suggest you have to know what is in it already. I might have that wrong, but still…. Don’t understand 😢
I must disagree with other commenters. This video does not “decode” a darn thing. For instance, how does one arrange the connected qubits for different algorithms? How are initial conditions determined and set? Hows does the algorithm recognize being done? Or how about a real problem that DOESN’T use Shor’s algorithm, like finding roots for a complex polynomial? Or address the mundane, like what does the “code” look like? I would call this video Fluff With Facts.
I understand it and at the same time I don't; however, there is a greater probability I will; providing I re-watch it, and rethink my position on how Quantum Computers work.
I don't understand how a quantum computer works... But I do hear many people who supposedly do understand quantum mechanics complain about how quantum computers "do not try all answers at the same time" and "that is not how quantum computers work".
Good interference through electromagnetic pulses may increase the probability of desired answer as superposition can generate many things . Decoherence is main issue here that is making qubits dance in a desired way😂 through our own music😂.
I think I'm with Einstein on this one. I'm just not seeing the use of outputting a completely non-deterministic state and applying a constructed state to resolve for an unknown state? It seems like you need to know how to influence the non-deterministic state to get a possible answer, which I feel like in many ways would be the answer itself (maybe its easier?). unless it's useful in some other way I'm not seeing (probably).
I figured error noise occurs because the suns radiation, maybe if you encased the computer in a cold and thick lead case the quibits would stay active to perform properly
With the best will in the world I still took nothing away from this video. Like many QC "explanation" videos there is no explanation of working. Only hype about what it could enable. If you strip away the waffle you get "Quantum computers work by using qbits in a clever way" .. and?
Google Sycamore was co-designed by me perhaps in the 1970s to the 1980s. But sure Google scientists would still come to me in MasbatePH in the 1980s for Sycamore. I knew I co-own Google that time, planned by me too, like Apple, Microsoft, Yahoo, Facebook, IBM, Intel, AMD, and Nvidia, and TSMC and ASML. The Chinese quantum computers were theorized and co-designed with me as early as the late 1970s. The Tamayos and Ramizos were advanced families of scientists researching and developing quantum computers. They pioneered modern computing's IBM PC, Apple computers, macOs and Windows operating systems, and microprocessors or microchips. Later, it was the Ramizos who became "academic" about computers including quantum computers (like writing for Scientific American "future" articles), while the Tamayos seemed to not cooperate. My mother and her Ramizo relatives or co-teachers had a quantum computer but would not easily share technology. The Americans, British, and Chinese had to go through children like me to get more quantum computing info. Though a kid, I was very prolific, even starting up and planning the tech giants.

20 qubits have 2^20 base vectors. The total number of states is every possible superposition of those base vectors, which is exponentially more than the number of state vectors themselves.
why cant i find an actual explanation of how a Qantum computer calculates things? like a normal computer is a complex sequence of diodes,makes sence. like Wat a basic adder wold look like in a quantum computer?
We don't know (yet). It's not even clear what "looking at" means. It might be when a conscious being makes an observation, or it might be something less mystical-sounding that that. But what *is* clear is that whatever the underlying mechanism, "normal" behavior down at those tiny sizes does not appear to be the same as it does in our everyday macro world.
