Brief Research Description

His current research interest is quantum information processing, particularly quantum cryptography. He was among the first to demonstrate the impossibility of a whole class of quantum cryptographic protocols including quantum bit commitment, thus correcting an erroneous long-held belief in the field. In a paper in “Science”, he and H. F. Chau provided a proof of security of quantum key distribution, thus solving a long-standing problem. Both results have been widely cited and also reported in the scientific press including “Science” and “Science News”.
