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 …

We report on the experimental realization and characterization of an asynchronous heralded
single-photon source based on spontaneous parametric down-conversion. Photons at 1550 …

There is no doubt that electronic communications have become one of the main pillars of the
modern society and their ongoing boom requires the development of new methods and …

Picosecond and femtosecond spectroscopy allow the detailed study of carrier dynamics in
nanostructured materials. In such experiments, a laser pulse normally excites several …

We report on a platform for the production of single photon devices with a fabrication yield of
100%. The sources are based on InAsP quantum dots embedded within position-controlled …

We first succeeded in generating single-photon pulses in the C-band (1.55-µm band: the
highest transmittance in optical telecommunication bands) from a single InAs/InP quantum …

Global, secure quantum channels will require efficient distribution of entangled photons.
Long distance, low-loss interconnects can only be realized using photons as quantum …

In this review, we report on fabrication paths, challenges, and emerging solutions to
integrate group-IV epitaxial quantum dots (QDs) as active light emitters into the existing …

We demonstrate that the emission characteristics of site-controlled InGaAs/GaAs single
quantum dots embedded in photonic crystal slab cavities correspond to single confined …
