Abstract: In this paper we present a genetic-algorithm-based search technique for linear optics schemes, performing two-qubit quantum gates. We successfully apply this technique to find heralded two-qubit gates and obtain schemes with performance parameters equal to the best currently known. Simple metrics are introduced which enable a comparison of schemes with different heralding mechanisms. The scheme performance degradation is discussed for the cases when detectors in the heralding part of the scheme are not photon-number resolving. We propose a procedure for overcoming this drawback which allows us to restore the reliable heralding signal even with non-photon-number-resolving detectors.
