It is actually a very crucial question: If the D-Wave machine is a just quantum computer emulator supported by classical hardware, we cannot expect much improvement in the future due to the inherent limitations of classical physics.
On the other hand, if it does behave like a quantum computer, it may end up being a lot faster than any classical computer.
- blackkettle 13y agojust curious but, why would you expect any appreciable improvement from the emulator version?
- bnegreve 13y agoGood question, I am not sure :) There can be many reasons. But the problem modeling is surely very different in its D-Wave form so the fact that there are improvements doesn't mean that it is because of quantum effects. Other than that, too limited experiments, comparing specialized vs general algorithms, sub optimal classical algorithms are also possible reasons.
- nolite 13y agoYou wouldn't, and right now, it's debatable whether there is any or not. Hence the entire controversy
- sampo 13y agoLet's keep in mind that the D-Wave machine is not a general purpose quantum computer. It only runs the quantum annealing, which is an aptimization algorithm, on its quantum register. This is the only thing the machine is able to do. http://en.wikipedia.org/wiki/Quantum_annealing http://en.wikipedia.org/wiki/Quantum_annealing
