The conference is devoted to quantum optics, primarily to the following areas: nonlinear processes in crystals, quantum interferometers, generation of non-Gaussian states, photon propagation in free space, quantum information with continuous variables, quantum correlations and entanglement, quantum imaging, quantum photonics and sensing, and quantum optical metrology. In addition, attention is expected to be paid to the connections between quantum optics and fields such as open quantum systems theory, quantum tomography, quantum control, quantum teleportation, and quantum technology.
