Questions tagged [superconducting-quantum-computing]

For questions about the superconducting realization of quantum computers. Questions can be about both the implementation of this realization or the theory behind this realization. If you are asking about a specific aspect of superconducting quantum computers, please also tag with that (i.e., if you are also asking about the Josephson junction, tag with that).

Superconducting qubit researchers: Do your TLS's move?

I have a superconducting system with tens of qubits, each of which can be tuned using DC flux. One of the main tasks for coherent manipulation of the qubits is to find good idling frequencies and operating points for entangling gates. This effort is…

Superconducting qubits and temperature

I would like to ask about the need of a low temperature for the operation of superconducting qubits. I know a superconducting qubit is made from basically a LC circuit and Josephson junction. So obviously, since Josephson junctions are made from…

Why superconducting qubits need periodic calibration?

I want to understand in some detail why superconducting qubits need periodic calibration. The usual, hand wavy explanation is environmental effects that tend to vary. However, I suspect that the actual picture is more complex than that. I want to…

Low yield rate of superconducting QPU fabrication?

What percentage of superconducting QPU chips are discarded after fabrication because of high error rate? Are some physical qubits significantly bad in state of the art superconducting QPUs? Are these two problems going to be a significant challenge…
