Curriculum Vitae, publication list,
I am a
theoretical physicist. Topics I have worked on in the past include the
connections between particle physics and cosmology, properties of topological
defects, nonperturbative phenomena in quantum field theory, and quantum aspects
of the early universe and of black holes. Since the mid-1990s, my central
interest has been in the theory of quantum information, quantum computing, and quantum error correction.
speaking, quantum information science addresses how the principles of quantum
physics can be harnessed to improve the acquisition, transmission, and
processing of information. A quantum computer would be a new type of machine
that, by exploiting the unusual quantum properties of information, could
perform certain types of calculations far more efficiently than any foreseeable
classical computer. I'm particularly interested in developing new schemes for
protecting intricate quantum systems from decoherence and other sources of
error. Here is a 6-minute
animated introduction to the subject.

In 2000 I
founded the Institute for Quantum Information (IQI), as part of the initiative in Information
Technology Research launched by the National
Science Foundation. In 2011 the IQI become a part of the Institute
for Quantum Information and Matter (IQIM), an NSF Physics
