Benchmarking imperfect implementations. Performance of photonic architectures (C: Clements39, in green; R: Reck38, in red, F: Fast, in blue) is investigated under realistic conditions of noise and losses. Throughout our analysis, simulations are carried out by introducing gaussian noise separately on both phase shifters (σ PS ) and beam splitters (σ BS ) in their Mach-Zehnder implementation. As figure of merit for their performance we adopt the fidelity39 and the total variation distance (TVD) to address more general applications involving also multiphoton evolutions.
