Abstract
A quantum cryptographic key distribution (QKD) transmitter includes an integrated photonic circuit configured to distribute encryption key material using quantum cryptographic mechanisms. The integrated photonic circuit further includes a first photon source, an interferometer coupled to the first photon source and a phase modulator coupled to the interferometer and configured to modulate a phase of photons emitted by the first photon source.
