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 …

Realization of a quantum interface between stationary and flying qubits is a requirement for
long-distance quantum communication and distributed quantum computation. The prospects …

Single-photon emitters play an important role in many leading quantum technologies. There
is still no'ideal'on-demand single-photon emitter, but a plethora of promising material …

Scalable photonic quantum technologies require on-demand single-photon sources with
simultaneously high levels of purity, indistinguishability, and efficiency. These key features …

Harnessing the full complexity of optical fields requires the complete control of all degrees of
freedom within a region of space and time—an open goal for present-day spatial light …

We report on the observation of nearly maximally entangled photon pairs from
semiconductor quantum dots, without resorting to postselection techniques. We use GaAs …

The combination of semiconductor quantum dots with photonic cavities is a promising way to
realize nonclassical light sources with state-of-the-art performances regarding brightness …

Recent progress in nanotechnology has allowed the fabrication of new hybrid systems in
which a single two-level system is coupled to a mechanical nanoresonator,,,,,,,,. In such …

The generation, measurement, and manipulation of light at the single-and few-photon levels
underpin a rapidly expanding range of applications. These range from applications moving …

We demonstrate laser-induced nonreciprocity of spin waves in the ferromagnetic-
semiconductor structure. Surface spin waves in yttrium iron garnet film grown at the top of n …
