Polarization Coded Quantum Key Distribution Through Telecom Single Mode Optical Fibers: Problems and Solutions
Guilherme B. Xavier, G. Vilela de Faria, Jean Pierre von der Weid · 2007
In this paper we briefly comment some technological limitations of the implementation of quantum crypytography employing polarization coding. We perform an experiment to demonstrate a compensation scheme for polarization coded QKD. We then apply a procedure to characterize an APD working as a photon counter operating in the single-photon regime. We finally perform a polarization coding photon counting experiment.
