Anyone interested in the D-wave story should be reading this article where Scott Aaronson explains the meaning of D-Wave's current results.
The takeaway points are:
- D-Wave's machine does demonstrate entanglement and quantum annealing
- There is no speed advantage whatsoever for quantum annealing over classical simulated annealing
- A correctly optimized version of classical annealing is actually faster than D-wave's solution
- D-Wave will only be able to make this machine work as a quantum computer (with the attendant speed gains) by implementing error-correction and other improvements that D-Wave have been loudly deriding for their entire history
