ooh. I'll check out the full video. My current work is on the hardware side of quantum computing

As Andrea said in the discussion, there is a ton of work for EE's and others in the quantum computing field.

I strongly recommend watching the whole video, its the best discussion about quantum computing i have heard, in regards to practical science. Very interesting video thanks EEV.

[@artyzinn7725]

One of the clearest description of quantum computing I've heard. Have not paid much attention to it from a practical side of engineering, but Morello makes it very easily understood and with as little physics jargon as possible. Making the complex sound simple is a reflection of high expertise. Kudos. On this side, his shirt is fascinating, it looks like a very densely routed PCB.

13:40 “But the nuclear spin of antimony has a spin of seven half, which means it has eight possible orientations of the spin of the nucleus.” Can someone 3blue1brown that for me, please?

[@stefan6889]

A spin of 7/2 means the spin projection number (i.e. the number of states) ranges from -7/2 to 7/2 in steps of 1: -7/2, -5/2, -3/2, -1/2, 1/2, 3/2, 5/2, 7/2, i.e. 8 states. It's quite analogous to a spin 1/2, which can be in the +1/2 state (spin up) or -1/2 (spin down).

I like the fact that he doesn't tolerate people calling quantum mechanics "weird" or "mysterious". People get intimidated out of learning reasonable concepts, like "imaginary" numbers, "complex" numbers, "convolution", etc. because the names make them sound more difficult than they really are.

[@TheRealFrankWizza]

AC voltage goes below 0. all the way to the opposite of it's high. You also need 4 pieces of information for 2 regular bits, as the second position of a binary counter is 3 out of 0-3 or the 4th digit if bit one and 2 are on. 0-15 looks like 1111 filling 4 bits with 16 digits. so on an so forth. AKA 2n

[@gustavgnoettgen]

I wish some one else would do anti static field experiments. I am currently doing my own and promising results. Because static can not work in zero degree temperatures there no sticking not conduction of static at those ranges in other words no interference. A static wick would be one example of anti static tech.

[@HayzerX]

How does spin up and down have different energy states? @23:53 the professor specifically mentioned high energy state (that enables escaping orbitals), aren't the spin and energy states different topics or is there a trick with the alignment of spins between the device and the electron? If they detect energy difference that enables an electron to escape an atom, wouldn't you relate it to the specific electron orbital where excitation is quantifiable with the jumps. Does the professor explain in the full video why there is a difference of 1.3 K between up and down? Is their device inducing a bias for spin down (or is it intrinsic somehow) and there is some energy leak that enables spin up at all since in order to get a 1.3 K difference it has to get that energy from somewhere?

[@TechyBen]

It does not, until another magnetic field is introduced. So, you set up the experiment, set up the "code" that is the arrangement of q-bits, and set your "result" to be when certain bits are up. If you get an up bit, you know the result was "up". If you get a different result (down, sideways etc) I guess they may have detectors for those orientations, or just take it as a null/zero result?

[@HayzerX]

@@TechyBen I think that its either 1 or nothing taking what the professor described - that they can only detect the "up" since it has enough energy to leave the atom and cause anything detectable with the current technology. But am I misunderstanding you, that they run a specific arrangement to get any results? So its basically a simulator where the coding is incredibly complex? The complexity lying in the transformation of an equation to be calculable with q-bits.

[@drscopeify]

Very cool! The question on my mind is will quantum computing kill encryption over the internet? Or will standard computing be able to increase encryption to keep up with quantum computing capability?

[@EEVblog]

Watch the full video. Short answer is no, not in any foreseeale timeframe. And yes, it adds to better encryption.

[@dinf8940]

no, it wont. as it is an erroneous interpretation of reality, the only place 'quantum computing' can be realized is simulation, and since that runs on standard computing and is terribly inefficient it will never threaten anything except in the mind of the plebeian dazzled by big words and magic

[@TechyBen]

@@dinf8940 Not really. It has limits and some encryption systems have already been hardened against known types of quantum decryption systems. QM is very much "real", and the computation if gives very much a known (though does have limits and probabilities that lead to failure rates, but so do classical computers fail at times).

[@SidneyCritic]

Why didn't USYD get this guy for their free public talks, because the heap of quantum talks I've seen there were pretty average, ie, too simplified. I like the higher level information, but thankfully he simplifies it enough that I can understand it - some of the medical ones there were over my head -.

[@cryptsys]

this dude looks so good for his age.

[@visageliquifier3636]

I think he misspoke at 11:30ish when he said there was 'more' information in two qbits because they describe four states, as this is true for all bits. In two bits I can encode four states: 00, 01, 10, 11. Those states may 'mean' different directions: up/up, down/down, same direction pointing out of the plane, or they can 'mean' numbers: 0, 1, 2, 3, but both is a list of four things. He also says at an 12:53 information density increases as 2^n vs n in a classical computer, which is not the case. If a bit can hold two states, then you can represent at least 2^n things in n bits, otherwise they are not bits. That is the nature of doing things in base-2. The extra information density of qbits comes in entanglement. When you force an entangled qbit to act one way, its entangled qbits take on symmetric behavior (as he stated previously!), allowing you to wire together data with decisions. It would be like having a solid that looked like a cup and saucer, but if you poured a hot liquid in to it, became a cup only, but if you dropped a slice of cake on it, became a plate only. Interfacing with it causes it to instantaneously change its behavior. If you entangle bits, you can have data that adjusts itself as you compute a different part of it, so you only have to do, say, half the work. It would be kind of like computing a long division problem, and as you drew each digit of the quotient you figured out, hazy pencil marks would coalesce elsewhere and by the time you wrote down three digits, the other three digits of the solution just ... appeared.
