Nonlocal random walk over Floquet states of a dissipative nonlinear oscillator
Yaxing Zhang, M. I. Dykman
We study transitions between the Floquet states of a periodically driven oscillator caused by the coupling of the oscillator to a thermal reservoir. The analysis refers to the osci…
Hardware-efficient quantum random access memory with hybrid quantum acoustic systems
Connor T. Hann, Chang-Ling Zou, Yaxing Zhang +4
Hybrid quantum systems in which acoustic resonators couple to superconducting qubits are promising quantum information platforms. High quality factors and small mode volumes make a…
Quantum state preparation for coupled period tripling oscillators
Niels Lörch, Yaxing Zhang, Christoph Bruder +1
We investigate the quantum transition to a correlated state of coupled oscillators in the regime where they display period tripling in response to a drive at triple the eigenfreque…
Engineering bilinear mode coupling in circuit QED: Theory and experiment
Yaxing Zhang, Brian J. Lester, Yvonne Y. Gao +3
Photonic states of superconducting microwave cavities controlled by transmon ancillas provide a platform for encoding and manipulating quantum information. A key challenge in scali…
Interaction-induced time-symmetry breaking in driven quantum oscillators
M. I. Dykman, Christoph Bruder, Niels Lörch +1
We study parametrically driven quantum oscillators and show that, even for weak coupling between the oscillators, they can exhibit various many-body states with broken time-transla…
