Optimization of a Polarization-Encoding System for Practical Quantum Key Distribution

Abstract: We present a method for optimizing the waveplate’s voltage range of an electro-optic based electrical polarization controller for qubit encoding in discrete-variable quantum key distribution (QKD). By increasing the number of used waveplates, the maximum voltage range to generate each of the states-of-polarization required by a QKD protocol can be reduced. The proposed machine learning algorithm, particle swarm optimization, was validated through numerical and experimental results. Results show that transition… Show more

“…Authors in [Co22] are using ML techniques to help the polarization controller in the receiver to compensate for the polarization random drift induced by the fiber. In this method additional waveplates is added to the polarization controller to have more controller over the phase retardation of the quantum signal.…”
