This is the final report for the AFRLRI in-house project Quantum Information Science. Under this project we constructed a six qubit quantum bit capable photon-based experimental testbed for the development of photon-based quantum gates and circuits and performed experimental and theoretical investigations of quantum computation. These investigations included theoreticalnumerical simulation 1 a hybrid coarsefine parallel simulation of Grovers quantum search algorithm 2 the development of a variant of Grovers algorithm that explicitly searches on one component of a database 3 the design of quantum optical gates by means of volume holography in photo-thermal refractive glass, and 4 an investigation of the advantage of utilizing cluster states for a one-way quantum computational paradigm experimental 5 the construction and validation of a group velocity matched temporal compensator crystal assembly to increase the usable range of entangled photon sources, and 6 the development and characterization of a new multipli-entangled photon source that increased the usable number of photon pairs by a factor of six.
