This review describes the emerging field of waveguide quantum electrodynamics concerned
with the interaction of photons propagating in a waveguide with localized quantum emitters …

The generation, manipulation, storage, and detection of single photons play a central role in
emerging photonic quantum information technology. Individual photons serve as flying …

An optimal single-photon source should deterministically deliver one, and only one, photon
at a time, with no trade-off between the source's efficiency and the photon …

Single photons are a fundamental element of most quantum optical technologies. The ideal
single-photon source is an on-demand, deterministic, single-photon source delivering light …

Photonic qubits are key enablers for quantum information processing deployable across a
distributed quantum network. An on-demand and truly scalable source of indistinguishable …

We realize an elementary quantum network node consisting of a silicon-vacancy (SiV) color
center inside a diamond nanocavity coupled to a nearby nuclear spin with 100-ms-long …

An outstanding goal in quantum optics and scalable photonic quantum technology is to
develop a source that each time emits one and only one entangled photon pair with …

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

Several emission features mark semiconductor quantum dots as promising non‐classical
light sources for prospective quantum implementations. For long‐distance transmission and …
