SPIE 5551, Quantum Communications and Quantum Imaging II, (19 October 2004); https://doi.org/10.1117/12.561697https://doi.org/10.1117/12.561697http://hdl.handle.net/11603/19363We review an experimental demonstration of a simple irreversible circuit of two probabilistic exclusive-OR (XOR) gates for single-photon qubits. We describe the operation of the individual linear-optics gates and the overall circuit in terms of two-photon and three-photon quantum interference effects. We also discuss future plans for quantum circuits using single-photon qubits from stored parametric down-conversion sources.9 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
