Quantum circuit synthesis via a random combinatorial search
Sahel Ashhab, Fumiki Yoshihara, Miwako Tsuji +2
We use a random search technique to find quantum gate sequences that implement perfect quantum state preparation or unitary operator synthesis with arbitrary targets. This approach…
High-frequency suppression of inductive coupling between flux qubit and transmission line resonator
Sahel Ashhab, Ziqiao Ao, Fumiki Yoshihara +2
We perform theoretical calculations to investigate the naturally occurring high-frequency cutoff in a circuit comprising a flux qubit coupled inductively to a transmission line res…
Controlling qubit-oscillator systems using linear parameter sweeps
Sahel Ashhab, Tomoko Fuse, Fumiki Yoshihara +2
We investigate the dynamics of a qubit-oscillator system under the influence of a linear sweep of system parameters. We consider two main cases. In the first case, we consider swee…
Extremely large Lamb shift in a deep-strongly coupled circuit QED system with a multimode resonator
Ziqiao Ao, Sahel Ashhab, Fumiki Yoshihara +5
We report experimental and theoretical results on the extremely large Lamb shift in a multimode circuit quantum electrodynamics (QED) system in the deep-strong coupling (DSC) regim…
