From: Quantum controlled-phase-flip gate between a flying optical photon and a Rydberg atomic ensemble
(Color online) (a) Schematic setup to realize the quantum controlled-phase-flip (CPF) gate between a flying photon qubit and a stationary atomic qubit. With a polarization beam splitter (PBS), the h polarization component of the single-photon pulse is reflected by the cavity, while the v polarization component is reflected via the mirror M. (b) The relevant level structure and transitions of the Rydberg atomic ensemble trapped in the cavity. (c) Schematic drawing for three resonant peak with three-level cavity-EIT system. The central peak results from dark resonance27.
