Career Highlight

            My current research interest is quantum information processing, particularly quantum cryptography. I 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”, I 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”. (See, for example, Charles Seife, Science 1997, May 16; 276: 1034 (in Research News) and Charles Bennett and Peter Shor, Science 1999, April 30, 284; 747-748. (in Perspectives).)

 

            Recently, my work on decoy state quantum key distribution, which appeared in Physical Review Letters, has attracted a lot of scientific attention and has been highlighted in a New Scientists article (Nov. 13, 2004). “This is one of the major recent advances in quantum cryptography. It should be relatively easy to implement.” Indeed, my group has now provided the first experimental demonstration of the idea.

 

I am a Founding Managing Editor of a leading journal, “Quantum Information and Computation” (QIC) in the field. The journal has been positively reviewed in the journal ``Nature’’. (See, Isaac Chung, Nature 420, p. 25. (7 Nov. 2002) (in Journal Review). ) Until Nov. 2002, I was the Chief Scientist and Senior Vice President for MagiQ Technologies, Inc., a company which is marketing commercial quantum cryptographic products (www.magiqtech.com ). Moreover, I have co-edited two books, one of which is a standard reference in the field and has been positively reviewed in the journal ``Nature’’.  I have written survey articles in leading scientific magazines (“Physics Today” and “Physics World”). In particular, my Physics Today article has been listed as a notable article in “The Best American Science and Nature Writing, 2001” edited by Ed. O Wilson. I am a co-inventor of one US patent, a European patent and several pending international patents.

           

I have been on the organizing or advisory and award committees of key conferences including QCMC 2000, QCMC'02, EQIS 2003, EQIS 2004, EQIS 2005, AQIS 06 and IEEE ISIT 2006.

 

I won four prestigious awards in 2003: I am a Canada Research Chair holder, an Ontario Outstanding Researcher, a co-winner of the year 2003 Outstanding Young Researcher Award by the Overseas Chinese Physics Association and a PREA (Premier’s Research Excellence Award) award holder. Earlier in my career, I won a Prince Philip Scholarship (a three-year merit-based full-cost scholarship) for studying at Trinity College, Cambridge University where I won Triple First Class Honors as well as a number of college prizes.

 

My research group currently contains two postdocs, five graduate students and a number of undergraduates as well as a fully equipped experimental/implementation lab in quantum communication.
