We propose an experiment in Linear Optical Quantum Computing (LOQC) in the style rst suggested by Knill,
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.
