Experimental Procedure to Characterize the Effects of Filtering and Decoherence on Polarization Entangled Photons

Abstract

We transmitted one photon of an entangled pair through a fiber channel that includes decoherence and partial filtering elements. We then demonstrated that a local filter could be applied to the other photon of the entangled pair in order to maximize the mutual quantum information between the photons. We showed that the relative orientation of the decoherence and filtering elements can be altered to emulate two types of noise, bit-flip noise and phase-flip noise, which are common to quantum channels. This note describes the exact experimental procedure that was followed to apply decoherence and filtering via polarization mode dispersion and polarization-dependent loss, respectively, to demonstrate our results.
