Superconducting qubit as a probe of quantum fluctuations in a nonlinear resonator
Maxime Boissonneault, A. C. Doherty, F. R. Ong +4
In addition to their central role in quantum information processing, qubits have proven to be useful tools in a range of other applications such as enhanced quantum sensing and as…
Quantum Heating of a nonlinear resonator probed by a superconducting qubit
F. R. Ong, M. Boissonneault, F. Mallet +5
We measure the quantum fluctuations of a pumped nonlinear resonator, using a superconducting artificial atom as an in-situ probe. The qubit excitation spectrum gives access to the…
Improved qubit bifurcation readout in the straddling regime of circuit QED
Maxime Boissonneault, J. M. Gambetta, A. Blais
We study bifurcation measurement of a multi-level superconducting qubit using a nonlinear resonator biased in the straddling regime, where the resonator frequency sits between two…
Measurement-induced qubit state mixing in circuit QED from up-converted dephasing noise
D. H. Slichter, R. Vijay, S. J. Weber +5
We observe measurement-induced qubit state mixing in a transmon qubit dispersively coupled to a planar readout cavity. Our results indicate that dephasing noise at the qubit-readou…
Backaction of a driven nonlinear resonator on a superconducting qubit
Maxime Boissonneault, A. C. Doherty, F. R. Ong +4
We study the backaction of a driven nonlinear resonator on a multi-level superconducting qubit. Using unitary transformations on the multi-level Jaynes-Cummings Hamiltonian and qua…
Circuit QED with a Nonlinear Resonator : ac-Stark Shift and Dephasing
F. R. Ong, M. Boissonneault, F. Mallet +7
We have performed spectroscopic measurements of a superconducting qubit dispersively coupled to a nonlinear resonator driven by a pump microwave field. Measurements of the qubit fr…
