Abstract

Systems and methods for performing polarization compensation in optical fiber-based quantum telecommunications systems are provided. The system includes a polarization modulator optically coupled to a photon source by an optical fiber and at least one controller coupled to the polarization modulator. The at least one controller is configured to determine, using a machine learning model and/or a lookup table, a feedback parameter based on one or more measurements of a polarization of probe photons at a location along the optical fiber, the probe photons being generated by the photon source; and using the feedback parameter, to change a setting of the polarization modulator to change a polarization of quantum data photons propagating in the optical fiber subsequent to the probe photons.
