This inspired a team of researchers at Kyoto University to investigate what they predicted may be a functional single-photon emission source. They hypothesized that a semiconductor in single-layer ...

As true single-photon sources (SPS) are difficult to produce, most QKD systems developed to date rely on attenuated light sources that mimic single photons, such as low-intensity laser pulses. As ...

A team of physicists at the Hebrew University of Jerusalem has made a breakthrough that could bring secure quantum communication closer to everyday use—without needing flawless hardware.
