BACKGROUND Semiconductor materials feature optical and electronic properties that can
be engineered through their composition and crystal structure. The use of semiconductors …

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 …

Chemically made colloidal semiconductor quantum dots have long been proposed as
scalable and color-tunable single emitters in quantum optics, but they have typically suffered …

The long dreamed 'quantum internet'would consist of a network of quantum nodes (solid-
state or atomic systems) linked by flying qubits, naturally based on photons, travelling over …

Quantum information science and engineering (QISE)—which entails the use of quantum
mechanical states for information processing, communications, and sensing—and the area …

Single-photon sources have recently been demonstrated using a variety of devices,
including molecules,,, mesoscopic quantum wells, colour centres, trapped ions and …

The fine structure of excitons is studied by magnetophotoluminescence spectroscopy of
single self-assembled In (Ga) As/(Al) GaAs quantum dots. Both strength and orientation of …

Quantum cryptography harnesses quantum light, in particular single photons, to provide
security guarantees that cannot be reached by classical means. For each cryptographic task …

The recent progress in integrated quantum optics has set the stage for the development of
an integrated platform for quantum information processing with photons, with potential …

We report coherent optical control of a biexciton (two electron-hole pairs), confined in a
single quantum dot, that shows coherent oscillations similar to the excited-state Rabi …
