(Nanowerk Spotlight) Quantum light sources are a fundamental building block for many quantum technologies, enabling secure communication, powerful computing, and precise sensing and imaging.

Superconducting undulators have become indispensable in the development of modern light sources, including synchrotrons and free electron lasers. By utilising arrays of superconducting magnets, these ...

Tiny tubes of carbon that emit single photons from just one point along their length have been made in a deterministic manner by RIKEN researchers. Such carbon nanotubes could form the basis of future ...

Nanolasers are ultrasmall laser devices with dimensions on the nanoscale. They generate coherent light through the process of stimulated emission, similar to conventional lasers, but at a much smaller ...

For hundreds of a millions of years, the universe existed in the dark ages—an epoch when only primordial gasses existed. Then, a period of reionization, cleared away this foggy existence an introduced ...

Quantum light generated through spontaneous four-wave mixing (SFWM) process in nonlinear materials, such as entangled photon pairs and single photons, is an important resource for various emerging ...

Chinese scientists are harnessing the capabilities of the science satellite SDGSAT-1 to tackle the growing issue of light pollution in urban settings. A recent study by the Aerospace Information ...
