I am the Brin Family Endowed Professor in Theoretical Computer Science at the University of Maryland. I am in the Computer Science department and a member of UMIACS and a QuICS Fellow. I got my Ph.D. at Caltech in 1997, and did
postdocs at Los Alamos National Lab and Microsoft Research, after
which I served in the UC Berkeley CS department as a Long-Term CMI
Prize Fellow with the Clay Mathematics Institute. I then spent 19 years as a faculty member at
Perimeter Institute in
Waterloo, Ontario before moving to Maryland.
Most of my work is in the field of quantum computation and quantum information. I have worked in a number of subfields, particularly quantum error correction,
fault-tolerant quantum computation, quantum complexity, and
quantum cryptography. I am best known for developing the stabilizer
code formalism for creating and describing a large class of quantum
codes, and for work on performing quantum
gates using quantum teleportation.
I was named to the MIT Technology Review's TR100:
Top Young Innovators for 2003 and I am an APS Fellow.

- Introduction to Quantum Information Processing (CMSC 657, UMD). This is a graduate-level semester course introducing the ideas of quantum information.
- Introduction to Cryptography (CMSC 456, UMD). This is an undergraduate course on classical cryptography.
- Quantum Complexity (CMSC 858L, UMD). This is a graduate course giving an overview of quantum complexity.
- Quantum Error Correction and Fault Tolerance. This is a semester graduate class for IQC taught either at PI or UW. The times it was at PI, the lectures were recorded. The course web pages contain problem sets and sometimes solution sets:
- PSI Quantum Information Review. This is an introduction to quantum information for Master's students at Perimeter. Each class consists of 14-15 one-hour recorded lectures:
Hobbies and Interests
I am married to Lucy Zhang. We have one son.
- Reading science fiction and fantasy
- Role-playing games
Here is a fairy tale I wrote one morning while I was in graduate school:
Snow White and the Seven Quarks. It should
not be taken to be representative of my own graduate experience.
Read my quantum error correction sonnet.
I was tapped to give an after-dinner speech at the QIP 2002
conference, and spoke about the penetration of
quantum computation into popular culture.
