Amusing historical note: D-Wave is so named because early in the company's history, we* wanted to do high-temperature, or even "desktop" quantum computing. In the process of hashing out implementation details, it became clear that the problem with operating at room temperature is thermal noise: the colder you go, the better your results. Turns out those d-wave superconductors wouldn't bring anything to the table, but many of them require tricky chemistry that would be much more complicated to fab than the metals we use. * "we" the organization, I wouldn't join in for years yet
