We review the rapid recent progress in single-photon sources based on multiplexing
multiple probabilistic photon-creation events. Such multiplexing allows higher single-photon …

Although universal quantum computers ideally solve problems such as factoring integers
exponentially more efficiently than classical machines, the formidable challenges in building …

Interfaced single-photon sources and quantum memories for photons together form a
foundational component of quantum technology. Achieving compatibility between …

Future multiphoton applications of quantum optics and quantum information science require
quantum memories that simultaneously store many photon states, each encoded into a …

Quantum memory is an important component in the long-distance quantum communication
based on the quantum repeater protocol. To outperform the direct transmission of photons …

The realization of a future quantum Internet requires the processing and storage of quantum
information at local nodes and interconnecting distant nodes using free-space and fibre …

An optical quantum memory can be broadly defined as a system capable of storing a
quantum state through interaction with light at optical frequencies. During the last decade …

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 …
