Single Photon Holographic Qudit Elements for Linear Optical Quantum Computing

Abstract : The operational objective of this project is to demonstrate that a small, lightweight, field-deployable, low-cost quantum algorithm (e.g. Grover's search algorithm) is feasible using existing technology. We have designed such optical elements and have begun a collaboration with CREOL (Leonid Glebov) to manufacture such gates for experimental demonstration of the results under this effort. Our technical objective of this project was the simulation and design of fundamental quantum logic gates, each encoded as a multiplexed volume hologram (VH) within a single piece of Photo-Thermal Refractive (PTR) glass. The approach we used to accomplished this is (1) the simulation of volume hologram on AFRL GP/GPU machines using a split-operator method , (2) mathematical modeling based on extensions of the coupled-mode theory, as well as (3) V&V.
