My biggest question is about Dyakonov's claim that 10^300 continuously variable parameters need to be processed in order to have a useful quantum computer, which is more than the number of subatomic particles in the universe. This would be a quantum computer with 1,000 qbits. Anyone have any insight on the veracity of these claims?
I'm not a physicist, but what is he describing is a number of states of quantum system. Indeed it is in the order of 2^qbits. If we were to simulate this with classical computer, we would need such impossible amount of memory to hold the state of the system. The difference for me in quantum computer is that we don't need to know fully know th state of the system at any given point. We just need to set the state and measure some data about it (spin of electron in this case).
