題目	Quantum memory and quantum processor based on cold atoms

摘要	Quantum science and technology has become a hot topic in recent years. The goal is to gain quantum advantage in applications like sensing, communication, computing and simulation utilizing the bizarre features of quantum mechanics, such as coherent superposition, quantum entanglement, uncertainty principle …etc. In this talk, I will introduce our efforts in the topic of quantum communication and computing. Specifically, I will first present our advancement on high-performance quantum memory (QM) based on electromagnetically induced transparency in cold atoms. Quantum memory is a device that can store photonic quantum states in stationary atomic media and retrieve on demand. It is a crucial component in long-distance quantum cryptography based on quantum repeater protocol. Our efforts towards high efficiency, high fidelity, and broad bandwidth of QMs will be reported. Finally, I will introduce our new project towards building a quantum processor for quantum computing and simulation based on two-dimensional single-atom arrays. The basic principle and recent progress will be reported.
