New light emitters developed for quantum circuits

​The promise of a quantum internet depends on the complexities of harnessing light to transmit quantum information over fiber optic networks. A potential step forward was reported today by WACQT researchers working at KTH who developed integrated chips that can generate light particles on demand and without the need for extreme refrigeration.

The new method enables photon emitters to be precisely positioned in integrated optical circuits that resemble copper wires for electricity, except that they carry light instead, says Associate Professor Ali Elshaari.
