Electromagnetically induced transparency in circuit quantum electrodynamics with nested polariton states
David P Pappas
NIST, USA
In this presentation, we report the observation of Electromagnetically induced transparency (EIT) in a superconducting circuit
system using strictly single-photon processes and polariton states in the nesting regime. EIT originates from quantum interference in
an atomic three-level system. To achieve this, we first drive the dressed cavity-qubit states of a two-dimensional circuit QED system.
This generates a set of polariton states. With proper tuning, we achieve the nesting regime, defined by the regime where the first two
levels of the Jaynes-Cummings ladder bracket the drive frequency. The lowest three energy levels of the polariton states are utilized
to form the $\Lambda$-type system. EIT is observed and verified by Akaike's information criterion based testing. Negative group
velocities up to $-0.52\pm0.09$~km/s are obtained based on the dispersion relation in the EIT transmission spectrum. This results in
a versatile, on-chip quantum-optics platform using tunable polaritons.
