3 sources of single photons: represented by a red dot at the center of the cavity, the semiconductor quantum dots (of nanometric size) is inserted in the center of the cavity, which consists of a 3 µm pillar connected to a circular frame by guides that are 1.3 µm wide. By applying electrical voltage to the cavity, the wavelength of the emitted photons can be tuned and the charge noise totally eliminated.

A new ultra-bright source of single photons Р15X brighter than commonly used sources and emitting photons that are 99.5% indistinguishable from one another Рhas been developed by researchers from the CNRS, Universit̩ Paris Diderot, and Universit̩ Paris-Sud...
