A new breakthrough in quantum light sources could make hacking a thing of the past.

Physicists working in the new field of meta-optics have made a breakthrough in the generation of polarization-entangled photon pairs that could allow quantum key distribution, a highly secure form of [...]


Spooky but tiny: grating boosts nanostructured quantum light source

A key element for future quantum technology is a step closer with the unveiling of a tiny quantum light source, less than one hundredth the diameter of a hair thick. [...]


Generating entangled photons with nonlinear metasurfaces

 A new method for generating quantum-entangled photon pairs employs nonlinear metasurfaces to enhance and tailor photon emissions—an important step towards creating miniaturized quantum devices for [...]
