Experimental quantum optics works on the arXiv in June 2019 included the generation two-dimensional cluster state on 30000 modes for continuous-variable quantum computing by Larsen et al. and a demonstration of a silicon quantum photonics platform for mid-infrared optics by Rosenfeld et al.. On the theory side, Malz and Cirac proposed a new design for photon number-resolving detectors based on atoms coupled to waveguides and Sadana et al. showed that double-slit interferometry can be studied as a lossy beam splitter.
