An Intracavity Rydberg Superatom for Optical Quantum Engineering: Coherent Control, Single-Shot Detection and Optical $\pi$ Phase Shift

Julien Vaneecloo, Sébastien Garcia, Alexei Ourjoumtsev

We demonstrate a new versatile building block for optical quantum technologies, based on an intracavity Rydberg-blockaded atomic ensemble acting as a single two-level superatom. We…
