It's more that D-Wave has gone off and abandoned the approach that everyone else is taking with their machine, so it's not clear if you can call it a quantum computer.
Imagine if I had a box that didn't have a cpu, or anything like a cpu, but could still solve a particular type of computing problem. It's kinda weird to call it a computer when it lacks the part that computes, but it still gets results for a subset of the problems.
On top of that, the D-Wave has far larger numbers, like it's 509 q-bits for this one, but it can't solve problems of the size we could if we had a 509 q-bit regular quantum computer. It's not really measuring the same thing.
- rdtsc 13y agoWell it sort of lives in both worlds. It does some some problems better, some not so much. It is a quantum computers as much as you can build a specialized FPGA or ASIC that does SHA256 hashes really well then kind of think, hmm, where I can use this awesome feature and what problems can be reduced to computing SHA256 hashes? Is that a "computer", well, kinda, maybe. > but it can't solve problems of the size we could if we had a 509 q-bit regular quantum computer. Well yeah because it is not really a universal computer and it is controversial and they are being sneaky about it.
