Proposed Experiment in Two-Qubit Linear Optical Photonic Gates for Maximal Success Rates

Abstract

Here we propose an experiment in linear optical quantum computing (LOQC) using the framework first developed by Knill, Laflamme and Milburn. This experiment will test the ideas of the authors previous work on imperfect LOQC gates using number-resolving photon detectors. We suggest a relatively simple physical apparatus capable of producing CZ gates with controllable fidelity less than 1 and success rates higher than the current theoretical maximum (S = 2/27) for perfect fidelity. These experimental setups are within the reach of many experimental groups and would provide an interesting experiment in photonic quantum computing.
