April 2019 in quantum optics included experiments on improving the noise resilience of qudit-based entanglement distillation by Ecker et al., the demonstration of a quantum dot source of indistinguishable single photons by Dusanowski et al., and an up-to-date review on novel architectures for photonic quantum computing by Takeda and Furusawa.
