Coherent dynamics of a photon-dressed qubit

Abstract

We consider the dynamics and stationary regime of a capacitively-shunted transmon-type qubit in front of a mirror, affected by two signals: probe and dressing signals. By varying the parameters of these signals and then analyzing the probe signal (reflected by the atom-mirror system), it is possible to explore the system dynamics, which can be described by the Bloch equation. The obtained time-dependent occupation probabilities are related to the experimentally measured reflection coefficient. The study of this type of dynamics opens up new horizons for better understanding of the system properties and underlying physical processes, such as Landau-Zener-Stuckelberg-Majorana transitions.
