Abstract

This paper expands upon prior work on an entangled photon source generating six pairs of photons via spontaneous parametric down-conversion in a single pass configuration. Experimental results measuring entangled photons at 810 nm are shown and other wavelength regimes will be discussed. The design and fabrication considerations for a group velocity matched (GVM) superlattice photon source are discussed. An application of this source enables various multiqubit cluster states to be generated in a compact unidirectional configuration. This configuration simplifies the interferometric stability for any associated feed-forward methods required in photon-based quantum logic circuitry.
