Extensible universal photonic quantum computing with nonlinearity
Universal quantum computing requires an architecture that supports both linear circuits and, crucially, strong nonlinear resources. For quantum photonic systems, integrating such nonlinearities...

New paper out in Phys. Rev. Research. We propose an all-photonic protocol that closes the detection loophole at the absolute Eberhard limit (η_d ≥ 66.7%) with √η_c loss scaling → loophole-free Bell tests over 100s of km with today’s tech. doi.org/10.1103/xw66-n…

Published in Physical Review A, we consider GBS-like circuits for non-Gaussian state engineering, where the measurement of a subset of modes adaptively reconfigures the subsequent layers, to maximise the success rate. doi.org/10.1103/jhkz-8…
