High-fidelity entanglement between a telecom photon and a room-temperature quantum memory

Yang Wang, Alexander N. Craddock, Mendoza, Jaeda M. +3 more

Entanglement distribution through existing telecommunication infrastructure is crucial for realizing large-scale quantum networks. However, distance limitations imposed by photon losses and the no-cloning theorem present significant challenges. Quantum repeaters based on entangled telecom wavelength photons and quantum memories offer a promising solution to overcome these limitations. In this work, we report an important milestone in quantum repeater architecture by demonstrating entanglement between a telecom-wavelength (1324 nm) photon and a room-temperature quantum memory with a fidelity up to 90.2%, using simple rubidium systems for both photon generation and storage. Furthermore, we achieve high-rate photon-memory entanglement generation of up to 1,200 Bell pairs per second with 80% fidelity. The technical simplicity and robustness of our room-temperature systems paves the way towards deploying quantum networks at scale in realistic settings.

Towards practical quantum repeaters using room-temperature vapor technology

Quantum entanglement sources and memories are critical for quantum networking architecture. For high-rate networking, it is important that both technologies are compatible with each other and existing fiber infrastructure. We present our work on the development of a bichromatic photon source (one in the telecom band and one at near-IR) based on warm atomic vapors. We characterize the source, and show our progress towards interfacing it with atomic memories. This paves the way towards building a quantum repeater node based on room-temperature technologies. These narrow linewidth photons are natively well-suited for interfacing with many quantum communication, computation and sensing technologies.
