Weve long known that D-Waves quantum computers are specialized tools rather than Swiss Army Knives, but just how good are they at their intended tasks? Google has just conducted some benchmarking to find out, and the short answer is that these systems are very good — but they have definite limits. A current-generation D-Wave 2 is about 35,500 times faster than a generalized problem-solving computer when both are running standard software.
