报告摘要：
Kirkwood-Dirac (KD) distribution is a representation of quantum states. Recently, KD distribution has been applied in many fields such as quantum metrology, quantum chaos, and the foundation of quantum theory. KD distribution is a quasi-probability distribution, and negative or non-real elements may indicate quantum advantages in certain quantum information processing tasks. If the KD distribution of a quantum state is a probability distribution, then the quantum state is called a KD classical state. Since most quantum information processing uses pure states as ideal resources, determining whether a quantum pure state is a KD classical state is a key problem. Recently, we have obtained some structural characteristics of KD classical pure states.
