One of the strangest features of quantum mechanics is also potentially its most useful: entanglement. By harnessing the ability for two particles to be intimately intertwined across great distances, researchers are working to create technologies that even Einstein could not imagine, from quantum computers that can run millions of calculations in parallel, to new forms of cryptography that may be impossible to crack. Join us as we explore the coming age of quantum technology, which promises to bring with it a far deeper understanding of fundamental physics.

Excellent panel with an awesome moderator. He asks pertinent questions, gives the guests equal time, and lets the panelists talk. No interjecting with corny jokes or pontificating on topics beyond his expertise (unlike one past moderator whom I shall not name).

32:08 I have been looking for a simple video explanation of Grover's algorithm running on a quantum computer. Jerry Chow explained it clearly. I am very grateful. Seems like in quantum programming, you start with all possible answers express in the number of entangled qubits and the encoded problem or your search for the answer is in the Oracle. Through a combinations of quantum gates, from all possible answers, one answer comes out as the right answer.

@_John_Sean_Walker 5 лет назад

Coach Normally, I enjoy channels like Nova and WSF a lot! But on this subject I want to pull their legs as hard as I can, but only to shake things up. For twenty five years they claim to present us the quantum computer next year. We are almost ready, they say. But when you look at this video you will notice that they avoid the question how we should program this computer. They come no further than an "or" and an "and" and when we ask a little further they start talking about a "search" or a security code. Literally everything they claim here the quantum computer can do, we already can do with a standard labtop. Except maybe that security code they speak of, but that one was cracked already during the development period, right here on RU-vid. And they admit that they want to crack YOUR security code, not increase your security. Who their client is, is unclear. Now imagine that you are programing a computer, and you have to jump to a subroutine (call) when a condition is true and just go on when false. When the bit is "1" you jump, and when the bit is "0" you just don't jump and go on with the rest of the program. This is the most basic and simple idea of any computer program. Now let them write the code for this conditional jump on their quantum computer when their "bit" is not 1 and not 0 at the same time. There is not a single soul on this entire planet that could answer this question. The quantum computer is NEVER going to work!

That an electron in the same quantum state can be seen in different location after several measurement doesn't mean that before measuring the electron was in several places "at the same time". Maybe is more adequate to say that the electron before measurement is "nowhere" precisely.

Proposed question Quantumn computing? Resolving Pi - Resolving Pi (First) Say you calculate Pi to 127 decimal points and then represent that as a spiral in 3D software, then in 3D modelling software take the 127th decimal point calculation and pull it outwards along the X axis…. Would the resulting analogy be a representation of containing infinity at least mathematically speaking? So instead of using an ‘X axis’ why not compute it around a circumference equation? Would you then have an infinite loop? Does that in effect resolve Pi? (Then) Creating Entropy in Robotic Systems So if you calculate that Last Formula (The description of resolving Pi) to 128 decimal places instead of 127 and then ‘calculate’ would that then create entropic failure in robotic systems to be used as a ‘Stop all failsafe program’ ?

Its almost as if this type of computer will not give me a direct answer, but rather a machine language answers of probabilities of what our questions are or in order to solve is, neither a yes or a no but rather, how?, then it seems if we want it(qubitcpu) to act like a traditional computer in the software created for this type of computing if its as simple as a question the quantum computer will according to what we want to do it almost as if it will created the gui interface for us of probabilities to check off as a control to come up with the defiabale 1, 0, binary in traditional computing anser that we can understand and envoke with like a few probabilities when it spits out the factoring gui then opions and then have to like in math reduce its answer to its simplest form.

Who uses computers to perform computations? I would say, Your average person uses computers for gaming or for social interactions. These are "underneath" computations. They serve a purpose but almost nobody really understands how or why they work. If you had a computer that runs every possible variation at once instead of three to five per a finite number of processors.

..it would take forever. The answer has to have an an intelligent question. The answer would be "42" because they don't know what the question is?

There is a great deal of hype surrounding quantum computing, but really, the results so far have been rather disappointing. The potential is there - but it's so difficult (and expensive!) to do the engineering, to create the software and get the performance that will outstrip any normal computers. But if that's what you want, don't hold your breath :0)

@AlexiLaiho227 5 лет назад

mathematicians always write about having a "maximally entangled system of n qubits" but we aren't even sure if that's physically possible. right now the primary problem is fidelity: if we had perfect quantum bits that never interacted with their environment unless we wanted them to, then we would've already achieved quantum supremacy at around the 40 qubit mark. but as he said during the video, we need to build ones that are like 400 qubits in order to make ones that have the same computing power as 40 idealized qubits, because of all of the wavefunction collapse. the main barrier is fidelity and isolating the system from outside influence.

Like Lloyd said, it sucks. The state of QC is such that you do not know what you are doing and what you want done (besides factoring huge primes). Maldecena claimed that the universe acts like a QC. Better still our senses, our brain (pineal gland) and all our cells have QC capabilities simulating protein production, moulding our behavior, sentiment and emotions etc., enabling us to make decisions, choices etc. No one studies these naturally occurring QC. Sure it is difficult to scientifically simulate and show how QC can help us invent new medicines or new algorithm etc. It is like when we discovered telescope we had to study the eye and find out how optics works (Ibn Haytum).

It is not going to happen next year, salaries do have to be payed, so keep funding please, otherwise the fun stops. Even when quantum decryption is getting closer (in a hundred years) we just make the keys a factor 1000 larger (doubling is not enough, I know) and decrypting is out of reach again. Let’s keep doing the research on quantum ‘computers’, let’s not make these idiotic promises for the near future. However, I do sleep much better now the QC has computed that 15 = 3 x 5.
