Scientists from Toshiba Research Europe Ltd. and the Cavendish Laboratory of the University of Cambridge have developed Entangled Light Emitting Diode.
The difference between this device and the emiconductor LED is that it contains a nanometer-scale quantum dot which produces the engtangled photons, so it makes quantum computing and highly secure optical networking possible.
According to the Cambridge, compact, cheap entangled emitters will be produced, and new applications will be created to exploit the quantum properties of light.
