Adiabatic frequency conversion of quantum optical information in atomic vapor

Frank Vewinger, Juergen Appel, Eden Figueroa, A. I. Lvovsky

abstract: We experimentally demonstrate a quantum communication protocol that enables frequency conversion and routing of quantum optical information in an adiabatic and thus robust way. The protocol is based on electromagnetically-induced transparency in systems with multiple excited levels: transfer and/or distribution of optical states between different signal modes is implemented by adiabatically changing the control fields. The proof-of-principle experiment is performed using the hyperfine levels of the rubidium D1 line.
