We study a system consisting of a superconducting flux qubit strongly coupled to a microwave cavity. Externally applied qubit driving is employed in order to manipulate the spectrum of dressed states. We observe resonance narrowing in the region where the splitting between the two dressed fundamental resonances is tuned to zero. The narrowing in this region of overlapping resonances can be exploited for long-time storage of quantum states. In addition, we measure the response to strong cavity…

Superharmonic resonances in a strongly coupled cavity-atom system
We study a system consisting of a superconducting flux qubit strongly coupled to a microwave cavity. The fundamental cavity mode is externally driven and the response is investigated in the weak

Dissipation in circuit quantum electrodynamics: lasing and cooling of a low-frequency oscillator
Superconducting qubits coupled to electric or nanomechanical resonators display effects previously studied in quantum electrodynamics (QED) as well as extensions thereof. Here, we consider a driven

TLDR
The joint activated dynamics exhibited by two quantum degrees of freedom: a cavity mode oscillator which is strongly coupled to a superconducting qubit in the strongly coherently driven dispersive regime and ensemble averaged amplitudes of both the cavity and qubit exhibiting a partial coherent cancellation are explored.
Qubit-oscillator system under ultrastrong coupling and extreme driving
We introduce an approach to studying a driven qubit-oscillator system in the ultrastrong coupling regime, where the ratio g/{Omega} between coupling strength and oscillator frequency approaches unity

Observation of the Bloch-Siegert shift in a qubit-oscillator system in the ultrastrong coupling regime.
We measure the dispersive energy-level shift of an LC resonator magnetically coupled to a superconducting qubit, which clearly shows that our system operates in the ultrastrong coupling regime. The
