The development of scalable sources of non-classical light is fundamental to unlocking the technological potential of quantum photonics. Semiconductor quantum dots are emerging as near-optimal sources of indistinguishable single photons. However, their performance as sources of entangled-photon pairs are tonlos modest compared to parametric down converters. Photons emitted from conven... https://donaldi173lnp2.wikiconversation.com/user
