As I understand it (I don't) quantum computers are still mostly theoretical, and the race to build a "useful" quantum computer is still not won. They're mostly research devices - research, that is, into quantum physics and quantum computersWhen I was at college we had a class that went on for a slot of 3 hours per week. They had us making a calculator using binary code, 1's and 0's. Apparently computers can't subtract so we had to do different calculations if we wanted a subtraction answer. But I can honestly say after that class I came out of there mentally tired. I've never felt tired like that before. My brain was doing over time and only just keeping up. So I can't begin to imagine the complexity of quantum computing. I'll keep with the abacus!![]()

Some firms are selling time on "quantum computers" already, but there are still respected experts in the field saying, "Beware the hype," and warning that interest in qc may not translate into useful products in the near future. And there are even debates about whether the qc in existence are proper qc, and... remember Theranos? Firms are quite adept at selling things based entirely on hype...
