Here are the quantum optics preprints that I found interesting in September 2019. Rahimi-Keshari et al. presented a new method for characterizing linear optics network (don’t miss the parable at the end of the manuscript!); Bell et al. demonstrated the much-needed technology of high-efficiency grating couplers to get photons on and off a photonic chip; and Gagatos and Guha showed that photon subtraction on multi-mode entangled Gaussian states cannot produce arbitrary non-Gaussian quantum states.
