Hark! Group Demonstrates First Heralded Single Photon Source Made from Silicon

Caption: This is an illustration of the process of photon pair generation, in which input pump photons spontaneously generate special pairs of new photons that emerge at precisely the same time, with one at a slightly lower frequency and the other a slightly higher frequency, after which heralding occurs.
