Optical photons are powerful carriers of quantum information, which can be delivered in free
space by satellites or in fibers on the ground over long distances. Entanglement of quantum …

An optical quantum memory is a device that can store photonic quantum information and
release it after a controlled time. It is an essential component for overcoming channel losses …

We demonstrate the storage and retrieval of an on-demand single photon generated by a
collective Rydberg excitation in a low-noise Raman quantum memory located in a different …

The T center, a silicon-native spin-photon interface with telecommunication-band optical
transitions and long-lived microwave qubits, offers an appealing new platform for both …

Abstract Machine-learning (ML) techniques are emerging as a valuable tool in experimental
physics, and among them, reinforcement learning (RL) offers the potential to control high …

High-performance quantum memories are an essential component for regulating temporal
events in quantum networks. As a component in quantum repeaters, they have the potential …

Broadband quantum memory is critical to enabling the operation of emerging photonic
quantum technology at high speeds. Here we review a central challenge to achieving …

We explore light storage in antirelaxation-coated and buffer-gas-filled alkali vapor cells,
employing electromagnetically induced transparency (EIT) in warm rubidium vapor. We …

Bose-Einstein condensates are a promising platform for optical quantum memories but
suffer from several decoherence mechanisms, leading to short memory lifetimes. While …

Superradiance, characterized by the collective, coherent emission of light from an excited
ensemble of emitters, generates photonic signals on timescales faster than the natural …
