Single-qubit Probe of a 1D Transmission Line Modified by Two Qubit Mirrors

ORAL

Abstract

A qubit that is strongly coupled to a 1D transmission line is known to reflect single-photon excitations, acting as a highly-reflecting qubit mirror. The presence of a qubit mirror modifies the mode environment in the 1D transmission line because the line’s right and left propagating modes are no longer independent. We experimentally probe the modified mode environment due to two such qubit mirrors arranged in a cavity-like configuration by exciting a third qubit—a probe qubit—that is also coupled to the transmission line. The relaxation of the probe qubit is enhanced / suppressed by the modified environment of the transmission line. We will discuss the connection of these results to the fluctuation-dissipation theorem.
