- Researchers have created an innovative new device that will emit single particles of light, or photons, from quantum dots that are the key to practical quantum computers, quantum communications, and other quantum devices https://www.eurekalert.org/pub_releases/2020-07/tcd-scn070720.php 5 comments technology
- Quantum dots typically emit light around 20 nanoseconds after being excited when at room temperature; new cesium lead halide quantum dots emit light at room temperature after just one nanosecond. Big advance in technology for optical computing & LEDs http://dx.doi.org/10.1038/nature25147 3 comments science
