Abstract

High-performance quantum memories are an essential enabling component for long-distance quantum networking with key applications including quantum key distribution, network-enhanced quantum sensing, distributed quantum computing, etc. Here, we present such a quantum device engineered to meet real-world challenges, while relying solely on room temperature (vacuum-free, cryogen-free) technologies. Based on a warm rubidium vapor, our device offers high-fidelity (94%), high efficiency (5%), long coherence time (up to 1ms), and low operation error (< 10−3), while only takes a standard 2U rackmount space. This result marks an important step transitioning from academic research into integrated and scalable devices working in the fields.
