Plug-and-play single-photon source can work at room temperature

The Korea Research Institute of Standards and Science (KRISS) has developed a room-temperature single-photon source built into a compact 19-inch rack-mounted device that operates without cryogenic cooling. Designed as a plug-and-play system that works as soon as it is powered on, the device moves quantum light source technology beyond the laboratory and closer to practical, onsite use.
