Abstract
A quantum circuit is presented. The quantum circuit includes a polarization dependent coupler optically coupled to a quantum source and a fiber loop, a polarization controller optically coupled to the fiber loop, wherein the polarization controller is configured to switch a polarization of a photon traversing the fiber loop, and a detector coupler optically coupled to the fiber loop and optically coupled to a photon detector.

A method of controlling photon propagation in a quantum circuit, comprising:
- directing a photon comprising a first polarization from a quantum source through a polarization dependent coupler and into a fiber loop,
- switching the polarization of the photon from the first polarization to a second polarization, using a polarization controller that is optically coupled to the fiber loop, during a first pass of the photon through the polarization controller such that the photon travels through the polarization dependent coupler and remains in the fiber loop for a second pass through the polarization controller;
- and
- disengaging the polarization controller prior to the second pass of the photon through the polarization controller such that the photon remains in the second polarization.
