Evidence for unexpectedly low quasiparticle generation rates across Josephson junctions of driven superconducting qubits
Byoung-moo Ann, Sang-Jun Choi, Hee Chul Park +6
Recent studies find that even drives far below the superconducting gap frequency may cause drive-induced quasiparticle generation (QPG) across Josephson junctions (JJs) of supercon…
All-microwave Lamb shift engineering for a fixed frequency multi-level superconducting qubit
Byoung-moo Ann, Gary A. Steele
It is known that the electromagnetic vacuum is responsible for the Lamb shift, which is a crucial phenomenon in quantum electrodynamics (QED). In circuit QED, the readout or bus re…
Resolving non-perturbative renormalization of a microwave-dressed weakly anharmonic superconducting qubit
Byoung-moo Ann, Sercan Deve, Gary A. Steele
Microwave driving is a ubiquitous technique for superconducting qubits (SCQs), but the dressed states description based on the conventionally used perturbation theory cannot fully…
Two-photon sideband transition in a driven quantum Rabi model : Quantitative discussions with derived longitudinal drives and beyond the rotating wave approximation
Byoung-moo Ann, Wouter Kessels, Gary A. Steele
In this work, we analytically and numerically study the sideband transition dynamics of the driven quantum Rabi model (QRM). We focus in particular on the conditions when the exter…
Motional resonances of three-dimensional dual-species Coulomb crystals
Byoung-moo Ann, Fabian Schmid, Jonas Krause +3
We investigate the motional resonances of dual-species Coulomb crystals comprised of Be and Mg ions held in a 4-rod linear Paul trap. Our experimental data and s…
Sideband transitions in a two-mode Josephson circuit driven beyond the rotating wave approximation
Byoung-moo Ann, Wouter Kessels, Gary. A. Steele
Driving quantum systems periodically in time plays an essential role in the coherent control of quantum states. The rotating wave approximation (RWA) is a good approximation techni…
