Generation of entangled waveguided photon pairs by free electrons
Generation of entangled waveguided photon pairs by free electrons
Entangled photons are a key resource in quantum technologies. While intense laser light propagating in nonlinear crystals is conventionally used to generate entangled photons, such schemes have low efficiency due to the weak nonlinear response of known materials and losses associated with in/out photon coupling. Here, we show how to …
