TL;DR: In this paper, a spectral filtering technique was proposed to increase the photon bunching signal in blackbody radiation via spectral filtering of the light source, including the Sun, in order to revive the interest in intensity interferometry as a tool in astronomy.

TL;DR: In this article, the authors demonstrate a quantum key distribution implementation over deployed dark telecom fibers with polarisation-entangled photons generated at the O-band, where one of the photons in the pairs are propagated through 10km of deployed fiber while the others are detected locally.

TL;DR: In this paper, the propagation of broadband photon pairs over deployed telecommunication fibers is used to achieve nonlocal dispersion compensation without the deliberate introduction of negative dispersion, made possible by exploiting time-energy entanglement and the positive and negative dispersive properties of the fiber.

TL;DR: In this paper, the authors demonstrate a technique for a dynamically compensating fibre-induced state alteration in a QKD system, which includes a feedback loop that minimizes the QBER using a stochastic optimization algorithm.
