A year ago I was in POK for executive briefing and they gave us a tour of the older quantum computer that they actually let people see. Pretty unimpressive as not much to look at, and the one thing that stood out to me was that it's an entirely analog machine. They were correct that they have a front end processor that converts your "program" to whatever it uses to load the quantum processor. This is blowing the computing world apart, and why ibm is also developing quantum safe crypto algorithms to keep things secure. I watched that 60 minutes story too. The clips that I assume were in POK were not in front of the quantum we saw.

I learned some things, but I still don't get it: 1) Scott Pelley describes the possible states of a bit (0 or 1), and then says "Quantum encodes information on electrons .. . [which] behave in a way so that they are heads AND Ok, I watched it. I learned some things, but I still don't get it: 1) Scott Pelley describes the possible states of a bit (0 or 1), and then says "Quantum encodes information on electrons ... [which] behave in a way so that they are heads AND tails and everything in between. You've gone from handling one bit of information to exponentially more data". Omitting the unfortunate misuse of "exponentially", if an electron can be in all states at once, how can a programmer, or the program, determine what data is recorded on it? I don't see how that can be true; they must be using impressive language to gloss over the details. 2) Michi Okaku likens the difference to calculating a path through a maze. A "classical" computer (his word) must check all possible turnings one at a time. But a quantum computer (he claims) "scans all possible routes simultaneously". I can't picture that, and therefore I'm doubtful; again, I suspect him of blathering about something that he really does understand but cannot describe accurately for a 60-Minutes audience. 3) We're shown a diagram of five Q-bits, and the voiceover says "Unlike transistors, each additional Q-bit doubles the computer's power". That is ~not~ "unlike transistors"; it's exactly what traditional bits do. "It's exponential", continues the voiceover, which, again, is exactly what classical bits are. "So, while 20 transistors are 20 times more powerful than one, twenty Q-bits are a ~million~ times more powerful...". Somebody should have vetted this sequence. 4) Karina Chou (sp?) of Google says their quantum computer is making an error about every 100 steps; they're aiming for one every million or so. Even at that target rate they surely need a lot of self-checking and self-correcting, no? 5) Dario Gill, when the interviewer asked whether programmers have to learn a new way of programming, responds "I think that's what's really nice, that you actually just use a regular laptop, and you write a program - very much like you would write a traditional program - but when you click on 'Go', it just happens to run on a very different kind of computer". I cannot reconcile this with the above nor with other statements being made about quantum computing. It's occurred to me that the whole quantum-computing mania might be no more than a huge hoax. I don't believe it, no. But so far I'm utterly clueless how to understand the claims about it. Regardless, thanks, Mr Sipples.
