dcterms:description
We present a systematic comparison of different methods of fidelity estimation of a linear optical quantumcontrolled-Z gate implemented by two-photon interference on a partially polarizing beam splitter. We utilize a linear fidelity estimator based on the Monte Carlo sampling technique as well as a nonlinear estimator based on maximum likelihood reconstruction of a full quantum-process matrix. In addition, we evaluate the lower bound on quantum-gate fidelity determined by average quantum-state fidelities for two mutually unbiased bases. In order to probe various regimes of operation of the gate we introduce a tunable time delay between the two photons. This allows us to move from high-fidelity operation to a regime where the photons become distinguishable and the success probability of the scheme significantly depends on the input state. We discuss in detail possible systematic effects that could influence the gate-fidelity estimation.
