- nick3443 2y agoDoes a superconducting semiconductor even make sense philosophically?
- throwaway81523 2y agoIt's a superconducting switch, not a semiconductor per se. Lookup "Josephson junction". IBM spent a fortune on a huge R&D program to make computers from this, but eventually abandoned it. I think they got some circuitry working but eventually decided it wasn't practical enough to commercialize. Also, some of today's work in quantum computers uses superconducting qubits. Maybe that's in the same research stage now. No idea if it will ever become practical. https://en.wikipedia.org/wiki/Josephson_effect https://en.wikipedia.org/wiki/Josephson_effect
