Abstract :
Elements of the coincidence-CNOT (controlled-NOT) are experimentally demonstrated, which includes a bright photon source with good spatial mode quality; nonclassical interferometry; improved photon detection; and tomographic analysis. The logical circuit of the coincidence-CNOT is described in the paper.
