Dynamics of measurement-induced state transitions in superconducting qubits
Yuta Hirasaki, Shunsuke Daimon, Naoki Kanazawa +3
We have investigated temporal fluctuation of superconducting qubits via the time-resolved measurement for an IBM Quantum system. We found that the qubit error rate abruptly changes…
