Why is the recent news around the LK-99 room-temperature superconductor such a big deal? What material impact would those findings have on electronics and modern technology?
Error correction relies on the majority of values to remain unchanged. I don’t think that assumption holds for qubits at room temperature. I’ll admit that I’m not well read enough to be certain.
Room temperature superconductors would be great for a lot of applications, but I don’t think they do that much to enable quantum computing.
Afaik superconducting quantum computers are operated well below the critical temperature for copper. They wouldn’t go through that extra effort if it wasn’t necessary.
