Abstract

We consider the dynamics and stationary regime of a capacitively shunted transmon-type qubit in front of a mirror. The qubit is affected by probe and dressing signals. By varying the parameters of these signals and then analyzing the probe signal (reflected by the "atom plus 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 the "qubit plus mirror"circuit properties and the underlying physical processes, such as Landau-Zener-Stückelberg-Majorana transitions. © 2023 American Physical Society.
