Abstract:

Quantum entanglement, “the spooky action at a distance”, is a peculiar feature of quantum theory. It plays a crucial role in the nonlocality of quantum mechanics. In quantum information processing, entanglement becomes an important resource for various tasks, such as teleportation, quantum computation, and cryptography. Intuitively, entanglement means a strong nonlocal correlation between distant parties, which essentially offers a secure key generation tool. Various Bell’s inequality test experiments have proved that eavesdropping (as a local hidden variable) can be fundamentally ruled out. In this talk, I shall link the basic concept of entanglement with the security of key distribution.

 

 

Biography：

Xiongfeng Ma’s main research interest lies on quantum information and quantum optics, particularly in quantum cryptography and correlation. After obtaining his BSc at Peking University in 2003, Xiongfeng attended the University of Toronto for his PhD degree. From 2008 to 2011, he did his post-doc and visiting positions at the University of Waterloo, the University of Toronto, and the University of Leeds. In 2012, Xiongfeng joined Tsinghua University as an assistant professor.
