Symmetry-based qubits allow Grover four-ports to serve as deterministic linear-optical CNOT gates with no post-selection or ancillae required.
Experimental tests of parity-check filters in a single-photon eight-mode photonic register on Quandela's Belenos processor show mean 0.6% DC leakage with 21x suppression and 94-99% syndrome channel selectivity.
Gradient-descent optimization of eight circuit parameters in a Strawberry Fields model yields CFI gains of 153% to 1775% and 8x to 133x more useful events per pulse versus Afek et al. (2010) for N=2-5, reaching 82% of Heisenberg limit at N=2 and 58% at N=5.
A literature survey of microwave-optical transduction across three platforms with two proposed normalized metrics for cross-platform comparison of efficiency and noise.
