Bacon-Shor code with continuous measurement of non-commuting operators
Juan Atalaya, Mohammad Bahrami, Leonid P. Pryadko +1
We analyze the operation of a four-qubit Bacon-Shor code with simultaneous continuous measurement of non-commuting gauge operators. The error syndrome in this case is monitored via…
Arrow of Time for Continuous Quantum Measurement
Justin Dressel, Areeya Chantasri, Andrew N. Jordan +1
We investigate the statistical arrow of time for a quantum system being monitored by a sequence of measurements. For a continuous qubit measurement example, we demonstrate that tim…
Measuring a transmon qubit in circuit QED: dressed squeezed states
Mostafa Khezri, Eric Mlinar, Justin Dressel +1
Using circuit QED, we consider the measurement of a superconducting transmon qubit via a coupled microwave resonator. For ideally dispersive coupling, ringing up the resonator prod…
Quantum Bayesian approach to circuit QED measurement with moderate bandwidth
Alexander N. Korotkov
We consider continuous quantum measurement of a superconducting qubit in the circuit QED setup with a moderate bandwidth of the measurement resonator, i.e., when the "bad cavity" l…
Measurement-induced state transitions in a superconducting qubit: Beyond the rotating wave approximation
Daniel Sank, Zijun Chen, Mostafa Khezri +21
Many superconducting qubit systems use the dispersive interaction between the qubit and a coupled harmonic resonator to perform quantum state measurement. Previous works have found…
