Pitch & Catch I: Deterministic State Transfer and Entanglement Between Remote Cavity Quantum Memories

ORAL

Abstract

Large quantum machines can benefit from a network architecture, where quantum communication channels between well-isolated subsystems are controlled on demand. One efficient communication scheme is direct, deterministic photon transfer as proposed in [1]. Utilizing RF-controlled parametric conversion, we realize this protocol between two remote millisecond-lifetime microwave cavity memories. We transfer a quantum bit between memories with high efficiency, achieving an average state fidelity that exceeds the classical bound. Furthermore, we extend this scheme in order to half-transfer a photon, generating high-fidelity entanglement between the two remote cavities. [1] Cirac et al, PRL 78 3221 1997
