Figure 1: Light propagation inside a photonic crystal is forbidden by a propagation gap, hence common plane waves are reflected and hardly penetrate into the crystal. By shaping the incident waves, they can be steered deep into the crystal. (Image: COPS, University of Twente)

A new single-photon avalanche diode system enables low-noise photon counting at superior speeds
Thorlabs has introduced the latest addition to its product line up for the field of quantum photonics, a correlated photon-pair source
The technique uses entangled photons to overcome the limitations of conventional holographic approaches
Taking advantage of collective quantum effects has enabled the so-called first quantum revolution in the 20th century for technologies such as nuclear magnetic resonance spectroscopy, magnetic resonance imaging, and the development of transistors, LEDs, solar panels, and lasers. Today, amid the second quantum revolution new sensing schemes offer higher sensitivities and better resolution thanks to the possibility to detect and control individual quantum states in microscopic systems like atoms, quantum dots, or color centers.
