The generation of entangled photon pairs, which are compatible with quantum devices and standard telecommunication channels critical for the development long-range fiber networks. Aside from wavelength, bandwidth matching, high fidelity produced pairs necessary interfacing efficiency. High-rate, robust entanglement sources that satisfy all these conditions remain an outstanding experimental challenge.
