Single-photon transmitter could enable new quantum devices

R&D Mag – MIT and Harvard University has achieved a crucial long-term goal of such efforts: the ability to convert a laser beam into a stream of single photons, or particles of light, in a controlled way. The successful demonstration of this achievement is detailed in Nature by MIT doctoral student Thibault Peyronel and colleagues.

In the new system, no matter how many photons are...
