An amazing video about the UC Santa Barbara Physics Department by MAT student James Darling documenting the quantum computing research done by Erik Lucero, who was a Ph.D student at UCSB at the time of this study. For more on this research, go here: www.ia.ucsb.edu/pa/display.asp...
Erik Lucero is currently part of John Martinis' group with UC Santa Barbara & Google. The group recently announced quantum supremacy with their Sycamore computer. Using 53 entangled quantum bits (“qubits”), the Sycamore computer has taken on - and solved - a problem considered intractable for classical computers.

Erik & crew - think about ESD protection when you handle the silicon. static clothes > movement > kV's charge > fries or weakens the silicon. You're carefully carrying the processor - but you're generating a charge - it's looking for the easiest discharge path. Been there done that. ~Bob, EE

We're on our way, I say. Remember, the first models of our Computer was just like this. One computer required one room, it was only able to compute numbers and nothing else, it has a separate room for the CPU, it's loud, it takes more than one person to make a computer work before. People thought it was impossible to finish. But not anymore. With quantum computers, we are doing the same thing again, but more ambitious.

Yes you can, because checking if a factorization is correct is straightforward: you just have to multiply the numbers together. If you get the wrong result, run the algorithm again. The probability that you'll never get the right answer is about (1/2)^n, which gets very small very quick.

This is such a complex subject and this is what is being made public about what is being discovered. It makes me wonder at times are even more amazing breakthroughs being made that we are unaware of. The problem of course is that some of these teams are being doomed to going down blind alleyways that will never work without realizing they have been visited before. Has anyone created a list of the different kinds of Quantum research techniques that is currently going on. (i.e like Seth Lloyd's work at MIT or the different approach Dwave are using) to try and define clearly methodologies and outcomes?.

Well let me explain it to you, 15 = 3x5 is integer factorization and those kinds of problems are 'easy-to-check', meaning if you are given a solution you can easily check whether they are correct or not. Keep this in mind. If I told you 987=3*7*47, you can immediately multiply 3 numbers and check whether I was right or wrong. 'Immediately' is compared to the time you would spend if I asked you the question "What is the integer factorization of 987?" Do you see how hard is it? So coming to the problem this quantum computer gives us the right solution 48% of the time, wow this is fantastic! I would be glad if I could get the right solution 0.001% of the time! Do you see why? Because I could feed the output of the quantum computer to a classical computer and let it check if the solution was correct. How long would it take? 1 ms? Well I certainly could run the quantum algorithm 1000 times, and check the output 1000 times, only 1 second overhead with these numbers. (Of course you would stop if you got the right solution inbetween 0-1000) The good thing is that integer factorization problem is easy-to-check as I just said. Consider TSP problem, given a path, can you easily check if it is the solution? Nah, you can't, as much as I know.

the qubit can be represented as a 0 or 1 or a superposition of (10). the best analogy is if you imagine a red door as a 0 or closed and a green door as 1 or open ..in classical computation these are the only doors available to use. in the quantum computer there is also a yellow door the superposition. let's imagine a maze of rooms with three doors. in order to make the best progress through the maze all the doors must lead to a solution ... however in the classical computer the doors can only be opened one at a time I.e red door blue door blue door red door. in quantum computer a yellow door is available as a tool to check both doors at once... so you have a headstart as each door is open the rate at which you progress thru the maze is n to the power of 2. this exponential trait is what sets quantum computers apart from classical dual bit computers as the function of the superposition ( yellow door ) which is not available to classical computers allows a quantum speed up. the example above denotes a single qubit however as you add more and more qubits the function of n to the power of 2 is multiplied by the number of cubits.

Yes, very very interesting, and a little disturbing. Maybe the proposition that we live in a multiverse has some legs. When we get down to the very fundamental level of nature, we arrive at a sort of gateway to other universes with different sets of physical/mathematical principles. 48% of the time the experiment shows that we are "here", and 52% of the time we are somewhere else, wherever that may be.

So in order to make it a functional computer. It needs an algorithm that runs what ever you are calculating several times, two arrays with each being run let's say 5 times , if the same value is returned 2 times out of 5 it returns that value to the first array. It does the same thing again and if it returns the same value twice out of five it returns that value as the correct value to the second array. Then it compares the arrays if they have the same value it returns it as the correct calculation and then proceeds to the next calculation, else it reruns the calculation. I think that would work.

Nar it'd just just return wrong answers the other 52%, but they'd probably be different wrong numbers, so the the right answer should still come out more often. And you can plug the factors into a classical computer and check whether they indeed equal the original number. That calculation is practically instant.

52% of times you get 15 = 7 x 3 or 15 = 1 x 4 and so on. That is not a problem since you can very easily see that they are false. It is just enough to hit the right solution once and check it. You see if the number was 2048bits long you could run it a hundred times and get 48 correct answers. Voila all you need is one correct answer. And that you will not get in traditional computing before lights go out literally.

Hypothetically (?), the self-organization of the Quantum Fields Mechanism, is what atomic structures in the Standard Model and Periodic Table are, all resonant summed history, phase-locked together in chemistry and physics, and are arranged according to the languages of mathematics in our perceptions to behave in particular "computed" ways of psudo-randomness. Ie if we can remove the "noise" of the annealing process, then a predetermined result of superposition will match the actual state output by the device, ("The Babbage accuracy of construction problem"). It's the ultimate parallel processing by design using an effect similar to the growth of spacetime-elemental grains (of primes) in crystal-coordinate resonance? Sum of all histories, now to now=>eternal constant/resonance. If the analog computation, (another name for an analogy by simplified comparison), is continued, then it's the readout of results that is the determining factor, (literally), of a successful operation, and so the methods and devices used in MRI, tuned to the desired range of solutions, is critical? (And possibly a compound set of scanning frequencies like WiFi in reverse..) It's analogous to the "hard problem" of mind in body, because it's a phase-locked distribution of QM-Time, Q-chemistry by Fields Modulation Mechanism e-Pi-i resonance embodiment. If coherence is disturbed, the content in context connection goes very wrong, because the singularity synchronisation of the Quantum principle is also the Quantum Operator of the Exclusion Principle. The nearest "device" analogous to the imagined operations of a Quantum Computer is possibly emulated by Human Savants, and that seems to be based on intense focus and vast memory storage with bio-logical Random Access (?) If structures, =events, within the Universe are resonance grains of spacetime, and bio-logical organisms are integrated multi-oscillator quantum information computation, insect colonies are hive-mind distributed computation, then brain-body organisms are integrated cellular hive-mind, up to the levels of self-recognition and "consciousness". Everything is phase-locked in resonance and timing spacing coherence/exclusion of cofactor-primes, AM-FM phenomena. One Multiverse ghost of coherence in one Quantum Computational Machine?

In my imaginings of better computing, I always thought that a knowledge base in 3D space, would become the standard. It would contain all of mankind's knowledge to date. A clone of Artificial Intelligences would have it as their base. But something I was reckoning on was 3D positioning could effect things by the interactions of actual electro/magnetically at some static level, would influence each other... but I did fail to say at the beginning this was for AI in 3D space... with the concept put forth that all knowledge has its place in logic compared to all other knowledge. And therefore would have its best positioning in 3D structure, a bit like a brain, but better. As it can be logically "wired" before it is designed to mass produced by machine into the solid unit. That is it evolves a Virtual add on for all its learning, so that in the next major upgrade, all of the AI's combine their data, so all get the new upgrade, either virtually or in the 3D mass produced new base model. Then again, it could be colours and crystals at some point, making binary a fraz of billions of colours...

If we had 10 million qubits working optimally we'd have enough computing power and data to store every electron, photon, and atom in the universe in so many different states that writing down the number of different state universes would take longer to write than the age of the universe.

The funny thing. 10 million qubits wouldn't be hard to achieve either. The hard thing is simply getting the architecture to work properly. We could already make a chip with that many qubits if not more, just wouldn't work.

If you have to "verify" the result using a traditional computer then you will have a problem. Consider Gödel's incompleteness theorems -- if you can solve a problem with a quantum computer that same problem will not be solvable on a traditional computer. If a quantum computer is only "sometimes" correct then you will never be able to verify an quantum answer by checking it on a conventional computer.

Seriously, people here are so hateful, these all people are like the dude who said,"There might be a market for only 10 computers." People don't realise how useful this technology is. This can enable you to exhaust near to infinite probabilities, like finding a new stable drug, simulating possible outcomes to complex problems, etc. These computers might not make it to your home, they are going to replace the supercomputers.

That's it? Nothing about how you used Shor's Algo to get to 15 = 3x5??? Well that was disappointing =( I get that it's a massive achievement to do that in a quantum computer, but I was hoping for a more indepth analysis / explanation of how you were able to get there. The Math. How the processor reached an equalibruim state. How you used a series of processes. This still seems like magic and wishful thinking to spend all this time trying to get a quantum computer to evaluate a complex system and have it spit out a result that may be 50% correct.

if so, why dont we look and try so simulate our brain and quantum computers and see how to stabilize the atoms since our brain apparently doesn't seem to be disturbed like quantum computers are disturbed by fucking anything and make the atoms go all over the place.

In a very simplified way, out brain is like a molecular computer, another variety of computer composed without the stress and randomness of quantum computers. Except it doesn't run like normal computers, constant electrical charges are coursing through the brain making permanent connections that take the form of memories and thought processes
