Xiao Tang (Assoc)

Dr. Xiao Tang, supervisory physicist, fellow of the American Physical Society, leads the Quantum communication project in the Applied and Computational Mathematic Division (ACMD) in the Information Technology Laboratory (ITL) at the National Institute of Standards and Technology (NIST). He holds an adjunct professor position at University of Limerick, Ireland.

Xiao joined NIST's ITL in June 1998. Currently, his research interest is focused on quantum communications, specifically, quantum repeaters and quantum networks, which is the nature extension of his previous research of quantum key distribution. Prior to that, he was a group leader managing the research activities of digital data preservation in the Information Storage and Integrated Systems (ISIS) Division. He was a leader of the NIST quantum communication testbed hardware group in 2001.  Before joining NIST, Xiao Tang was a research associate professor in the Materials Science Research Center at Howard University, Washington DC, worked on wide-bandgap semiconductors. In the latter 1980's, he was a deputy director of Pohl Institute of Solid State Physics and an associate professor in the Department of Physics at Tongji University, Shanghai. Before 1985, he was with the Institute of Physics, Chinese Academy of Sciences in Beijing, where he developed the first Chinese semiconductor laser capable of continuously operation at room temperature in early 70’s.
