报告摘要：

We study quantum properties of light, such as nonclassicality, entanglement, and general quantum correlations.We start by introducing the notions of nonclassical and entangled quantum states and identify their origin in the quantum superposition principle. Some examples for experimental reconstructions of quantum states are given. Properties of nonclassical states are discussed with particular emphasis on squeezed states. We introduce a method to visualize the nonclassicality of such quantum states in experiments by direct sampling of the so-called nonclassicality quasi-probability. The verification of quantum entanglement is considered for complex multi-partite scenarios. We also developed a numerical technique to verify non-Gaussian entanglement. Finally we consider general, space-time-dependent quantum correlations of light. Quantum correlations can be certified even when other signatures of quantumness fail.
