Noob question. Does this breakthrough also translate to advancements in quantum computing? Can we expect quantum computers with far more qbits?
- scarmig 3y agoNope. Quantum computing requires low temperatures not because of resistance but to maintain coherence.
- seewhydee 3y agoA room temperature superconductor would, by definition, maintain quantum coherence (of the superconducting order parameter) at room temperature.
- sudosysgen 3y agoThat's not what is meant by coherence, what is required in a quantum computer is for multiple qbits to maintain states coherent to each other. Current quantum computers operate in the milikelvin range for a reason, despite superconductors working at 1000x higher temperatures.
- qnleigh 3y agoIt won't have a direct impact on quantum computing. People make qubits out of superconducting materials that become superconducting at 4K or higher, but you have to cool them to around 0.03 K for them to really work well as qubits. See https://en.m.wikipedia.org/wiki/Superconducting_quantum_computing https://en.m.wikipedia.org/wiki/Superconducting_quantum_comp.... But there could very well be indirect applications! This would be very very interesting for the physics community, and surely lead to other new things.
