Entanglement distribution over 150 km in wavelength division multiplexed channels for quantum cryptography
Abstract Granting information privacy is of crucial importance in our society, notably in fiber communication networks. Quantum cryptography provides a unique means to establish, at remote locations, identical strings of genuine random bits, with a level of secrecy unattainable using classical resources. However, several constraints, such as nonāoptimized photon number ā¦
