Worldwide, enormous efforts are directed toward the development of the so‐called quantum
internet. Turning this long‐sought‐after dream into reality is a great challenge that will …

Lasers and LEDs have a statistical distribution in the number of photons emitted within a
given time interval. Applications exploiting the quantum properties of light require sources …

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 …

We have demonstrated efficient production of triggered single photons by coupling a single
semiconductor quantum dot to a three-dimensionally confined optical mode in a micropost …

Fast, high efficiency and low error single-photon sources are required for the implementation
of a number of quantum information processing applications. The fastest triggered single …

In 1954, Dicke pointed out that the description of a spontaneously radiating gas has to
include the fact that all atoms or molecules interact with a common radiation field …

Currently, metal–halide perovskite semiconductors have attracted enormous attention for
their excellent optical performance. However, challenging issues, such as the ability to …

Cavity quantum electrodynamics, the study of coherent quantum interactions between the
electromagnetic field and matter inside a resonator, has received attention as both a test bed …

We demonstrate the triggered emission of polarization-entangled photon pairs from the
biexciton cascade of a single InAs quantum dot embedded in a GaAs/AlAs planar …
