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

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.
