Abstract

An apparatus providing an integrated waveguide device that creates entanglement between a sequence of periodically spaced (in time) photons in a single input and output mode. The invention comprises a polarization maintaining integrated waveguide chip containing a number of delay lines, integrated multimode interferometers with the potential for rapid switching, a polarization controller and off chip computer logic and timing.

First claim

What is claimed is:

1. An apparatus for sequentially entangling photons, comprising:
a waveguide chip having integrated optical components and interconnecting optical waveguides disposed therein, wherein said optical components further comprise
an input port connected to said optical waveguides for inputting said photons into said waveguide chip;
a polarization controller connected to said input port for rotating the polarization of said input port;
a plurality of delay line…
