Electromagnetically induced transparency in a tunable three-dimensional transmon
ORAL
Abstract
Electromagnetically induced transparency (EIT) has been realized in atomic systems, but fulfilling the EIT conditions for artificial atoms made from superconducting circuits is a more difficult task. Here we report an experimental observation of the EIT in a tunable three-dimensional transmon by probing the cavity transmission. We tune the transmon to adjust its damping rates to fulfill the EIT conditions. From the experimental observations, we clearly identify the EIT and Autler-Townes splitting (ATS) regimes as well as the transition regime in between. Also, the experimental data demonstrate that the threshold $\backslash $Omega\textunderscore \textbraceleft AIC\textbraceright determined by the Akaike information criterion can describe the EIT-ATS transition better than the threshold $\backslash $Omega\textunderscore \textbraceleft EIT\textbraceright given by the EIT theory.
