THE FACT ABOUT PPKTP CRYSTAL THAT NO ONE IS SUGGESTING

Within this presentation experimental final results of a two-photon interference experiment will probably be offered and reviewed. The 2 photons, made by parametric downconversion inside of a KNbO3 crystal, had been analyzed with two interferometers bodily separated by more than 10 km with the source around at the middle.Example: Just one PPKTP cry
