Single photon counting, based on single photon sources and detectors, is a key ingredient
for certain applications aiming at new quantum information technologies. Quantum …

We report the observation of beatings of the coincidence event rate in a Hong-Ou-Mandel
interference (HOMI) between signal and idler photons from a parametric downconversion …

We demonstrate a bright, narrowband, compact, quasi-phase-matched single-crystal source
generating path-polarization-entangled photon pairs at 810 nm and 1550 nm at a maximum …

We propose an efficient hyperentanglement source emitting photon pairs entangled in both
energy and polarization. The compact electrically driven room-temperature source, based …

We present a simple quantum-field model for photon frequency conversion processes in
dispersive dielectric microcavities, allowing practical calculations of conversion rates and …

We experimentally demonstrate a phasematching technique for frequency conversion in
nonlinear semiconductor structures by employing linear long-period gratings. We designed …

Quantum key distribution is among the foremost applications of quantum mechanics, both in
terms of fundamental physics and as a technology on the brink of commercial deployment …

In this paper we show that by suitably tailoring the dispersion characteristics of a Bragg
reflection waveguide (BRW) mode, it is possible to achieve efficient photon pair generation …

We show that the angular spectrum of type-II SPDC contains a continuum of maximally
entangled states. For the realization of a bright source of entangled two-photon states, a …

In this work we present optical setups for a polarization encoded qubit, based only on
common linear optical devices, which implement probabilistic bipartite and tripartite …
