Description

This invention consists in an apparatus for the production of photons where each photon is characterized by two entangled degrees of freedom. It consists of a photon source and an entanglement generation stage between two selected states of a single photon. The apparatus can be formed by discrete components or can be fully or partly realized with an integrated optical circuit.
