Comment on Regarding this picture, where do you think quantum computers lie and why?

It’s debatable if D-Wave is actually a quantum computer at least in the sense most people use the term. There’s a lot of unanswered questions still on exactly how to use and design a quantum computer and we’re not likely to get those answers until we can reliably produce and run systems with at least 8 qubits. Maybe DARPA and the military/CIA has such systems, but I don’t think anyone else does.

Quantum computers are still mostly theoretical. We have some of the building blocks of one, but there’s still a few critical pieces missing. Quantum computers are in about the same place as fusion reactors are. Theoretically possible but not currently producible in a form that’s useful without a few more technological breakthroughs.
