Resources

Technical

Prof. John Preskill teaches a course on quantum information at Caltech. Lecture notes.

Several universities have research and teaching activities in quantum information processing. Among these are:

• MIT, efforts in many departments and labs.
• Institute for Quantum Computing, University of Waterloo.
• Centre for Quantum Computation, University of Oxford.

One of the most active industrial research groups in quantum information is at IBM Research Yorktown. This was the home of one of the early leaders in the field, the late Rolf Landauer, and younger people including Charles H. Bennett, who is known for many contributions including his work on quantum teleportation. Another active group is the Quantum Information Processing Group at Hewlett-Packard Laboratories, Bristol, UK.

Historical

• Rolf Landauer obituary.
• Richard P. Feynman biography. Feynman, an MIT graduate, was curious about the nature of quantum information.

Books

There are already many books and conferences on quantum information, even though the field is new.

• Hoi-Kwong Lo, Sandu Popescu, and Tim Spiller, “Introduction to Quantum Computation and Information,” World Scientific, Singapore; 1998. The book is based on a lecture series held at Hewlett-Packard Laboratories, Bristol, UK, November 1996 – April, 1997.
• Michael A. Nielsen and Isaac L. Chuang, “Quantum Computation and Quantum Information,” Cambridge University Press, Cambridge, UK; 2000. This is probably the best of the books intended for scientists and engineers. Chuang, an MIT graduate, is currently on the MIT faculty.
• Dirk Bouwbeester, Artur Ekert, and Anton Zeilinger, editors, “The Physics of Quantum Information: Quantum Cryptography, Quantum Teleportation, Quantum Computation,” Springer-Verlag, Berlin, Germany; 2000.
• Jeffrey H. Shapiro and Osamu Hirota, editors, “Proceedings of the Sixth International Conference on Quantum Communication, Measurement and Computing,” July 22–26, 2002, Cambridge, MA; Rinton Press, Princeton, NJ; 2003.
• George Johnson, “A Shortcut through Time: The Path to the Quantum Computer,” Alfred A. Knopf, New York, NY; 2003. This book, written by a New York Times science writer, is for the general public and may not be technical enough for some readers.

James Clerk Maxwell opened up the relationship between information and entropy by proposing what is called today Maxwell’s Demon, which would apparently violate the Second Law of Thermodynamics. Maxwell’s Demon in its many forms has captured the imagination of both scientists and the general public.

• Leon Brillouin, “Science and Information Theory,” Second Edition, Academic Press Inc, London, England; 1962. Topics include Brownian motion, thermal noise, information theory, entropy, and the author’s personal view of Maxwell’s Demon.
• Harvey S. Leff and Andrew F. Rex, “Maxwell’s Demon: Entropy, Information, Computing,” Adam Hilger, Bristol BS1 6NX, England; 1990. General historical discussion with many reprints of original papers but not, regrettably, any of Maxwell’s own publications.
• Hans Christian von Baeyer, “Maxwell’s Demon,” Random House, New York; 1998. A very good review for the general public, by a Professor of Physics at the College of William and Mary, this book was written before the quantum version of the demon was understood as well as it is today.
