Measurement-Induced State Transitions in a Superconducting Qubit: Within the Rotating Wave Approximation

Mostafa Khezri, Alex Opremcak, Zijun Chen +9

Superconducting qubits typically use a dispersive readout scheme, where a resonator is coupled to a qubit such that its frequency is qubit-state dependent. Measurement is performed…
