Abstract : This is the final report for the AFRL/RI in-house project Cluster State Quantum Computation. Under this project investigations were conducted which included: (i) the development and characterization of a new multipli-entangled photon source that increased the usable number of photon pairs by a factor of six over conventional entangled photon sources; (ii) design of multi-layer superconducting number-resolving photon detector, (iii) a theoretical and experimental investigation into the requirements of imperfect (non-unit fidelity) two-qubit linear optical photonic gates; (iv) a theoretical investigation of entanglement and nonlocality addressing the issue of why nature does not take advantage of the algebraically allowed maximum correlations amongst collections of qubits, and (v) a theoretical investigation into the a 2.25X more efficient means to generate linear cluster states. This latter investigation led to a patent for probabilistic cluster state generator, also discussed in this report.
