Emergence of atom-light-mirror entanglement inside an optical cavity

TL;DR

This paper proposes a scheme to generate and analyze robust tripartite and bipartite entanglement among atoms, light, and a vibrating mirror within an optical cavity, demonstrating potential for quantum information applications.

Contribution

It introduces a novel hybrid system combining atomic ensembles, optical cavities, and vibrating mirrors to produce steady-state entanglement under realistic conditions.

Findings

Steady-state tripartite entanglement is achievable in the proposed system.

Entanglement persists at experimentally accessible temperatures.

The system exhibits both bipartite and tripartite continuous variable entanglement.

Abstract

We propose a scheme for the realization of a hybrid, strongly quantum-correlated system formed of an atomic ensemble surrounded by a high-finesse optical cavity with a vibrating mirror. We show that the steady state of the system shows tripartite and bipartite continuous variable entanglement in experimentally accessible parameter regimes, which is robust against temperature.
