Ultrafast remote switching of light emission

Researchers can now for the first time remotely control a miniature light source at timescales of 200 trillionth of a second. Physicists have developed a way of remotely controlling the nanoscale light sources at an extremely short timescale. These light sources are needed to be able to transmit quantum information.
