Description
Abstract
Quantum communication can provide information theoretical security. The main obstacle to limit its application is the channel loss and implementation security. I shall give a review of the research towards long distance and (semi-) device independent quantum communication.
Biography
Qiang Zhang received the B.S. degrees and the PH.D. degree in Physics from University of Science and Technology of China (USTC), Hefei, China in 2001 and 2006, respectively. Then he worked as a postdoctoral research fellow in Ginzton Laboratory, Stanford University, USA from Oct. 2006 to Mar. 2011. In Apr. 2011, he joined in Hefei National Laboratory for Physical Science at Microscale, USTC as a professor. His research primarily focuses on the field of quantum information and has made contribution to most key building blocks of the development of core components and key technology in the field of quantum communication. Examples of his key achievements include: He experimentally demonstration of a measurement device independent quantum key distribution (MDIQKD) and set a world record for fiber experimental quantum cryptography realizations by extending the effective transmission distance to 509 km. He experimentally realized the first device-independent quantum random number generation and quantum teleportation over a metropolitan fiber network. He has published more than 90 articles in peer-reviewed journals, including 1 in Review of Modern Physics, 5 in Nature, 9 in Nature Sub journals and 29 in PRL(X). His research achievements were recognized by American Physical Society ("APS") as "Highlights of the Year 2013", as "Top 10 Chinese Research Progress News" in 2006 and 2014 respectively and as "Top 10 Chinese Science News” in 2019. He was the chair of the flagship meeting in the field of quantum cryptography, QCrypt in 2008 and 2020. Recently, he was elected as the co-chair of the first standardization focus group of Quantum Information Technology-- ITU Quantum Information Technology Focus Group in 2019.
