Observation of coherent flux-charge interaction in a gate-tunable fluxonium
Brian D. Isakov, Shikhar Singh, Adrian Parra-Rodriguez +7
Interactions that mix conjugate variables, such as the flux through a circuit element and the charge across it, lie outside the reach of the elementary couplings of superconducting…
Measurement-induced state transitions across the fluxonium qubit landscape
Alex A. Chapple, Boris M. Varbanov, Alexander McDonald +1
Understanding the mechanisms that limit high-fidelity readout in circuit quantum electrodynamics is essential for its optimization. Multi-photon resonances are understood to be a l…
Absence of Charge Offset Drift in a Transmon Qubit
Adria Rospars, Hector Hutin, Yannick Seis +8
Superconducting quantum circuits are sensitive to their electrostatic environment: uncontrolled charges accumulating on the electrodes of a Josephson junction shift the energy leve…
Quantum optimal control of superconducting qubits based on machine-learning characterization
Elie Genois, Noah J. Stevenson, Noah Goss +2
Implementing fast and high-fidelity quantum operations using open-loop quantum optimal control relies on having an accurate model of the quantum dynamics. Any deviations between th…
Optimal control in large open quantum systems: the case of transmon readout and reset
Ronan Gautier, Élie Genois, Alexandre Blais
We present a framework that combines the adjoint-state method together with reverse-time backpropagation to solve prohibitively large open-system quantum control problems. Our appr…
Dissipation and Ultrastrong Coupling in Circuit QED
Félix Beaudoin, J. M. Gambetta, A. Blais
Cavity and circuit QED study light-matter interaction at its most fundamental level. Yet, this interaction is most often neglected when considering the coupling of this system with…
