This project considers receivers that measure polarization in the Pauli <math>Z</math> and Pauli <math>X</math> bases (a passive-basis-choice "BB84 measurement"). Such a receiver consists of a polarization analysis module (PAM) followed by single-photon detectors. A simple schematic is given below. <pre>..."
