Abstract

We propose an experiment in Linear Optical Quantum Computing (LOQC) in the style rst suggested by Knill, La amme, and Milburn. This experiment is intended to test the theories proposed in the authors' previous work on imperfect LOQC gates using number-resolving photon-detectors. We develop a simple physical apparatus capable of producing controllable delity less than 1 and success rates higher than the current theoretical maximum (S=2/27) for perfect delity. This experimental setup is within the reach of many experimental groups and would provide an interesting experiment in photon-based quantum computing.
