Title: Quantum Error-correction Codes

Date: Tuesday, 12 June 2001

Time: 3:00-4;00pm

Venue: Room 4480, Phase II (via lift nos. 25/26), HKUST

Abstract:
Quantum codes were proposed five years ago by Calderbank, Shor, Steane et al., and have important applications in quantum computing, communication and cryptography. This talk will introduce basic mathematical conceptions of quantum codes, mathematical methods to construct good QC by using character theory of finite abelian groups and 'classical' coding theory, and some open problems.

Biography:
Prof. Feng graduated from the China University of Science and Technology in 1962 and 1968 for his undergraduate and graduate study respectively. He then worked for a company for five years. In 1973 he joined the China University of Science and Technology and became a professor in 1985. He moved to the Beijing Graduate School of the China University of Science and Technology in 1996 and taught there for three years. At the same time he was the Director of the National Information Security Lab in Beijing. He joined Tsing Hua University in 2000, and is now the Head of the Department of Mathematics.

His main research topics include algebraic number theory, coding theory and cryptography.
