Lloyd, Seth. "Quantum-Mechanical Computers." Scientific American 273 (October 1995): 44-49.
An early, very readable description of quantum computation.

Spiller, T. P. "Quantum Information Processing: Cryptography, Computation, and Teleportation." Proceedings of the IEEE 84 (December 1996): 1719-1746.
Although this paper is several years old, it provides an excellent introduction for students.

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 Bennett, who is known for his work on quantum teleportation.

Historical

Rolf Landauer (1927-1999) obituary

Richard P. Feynman (1918-1988)
Feynman, an MIT graduate, was curious about the nature of quantum information.

James Clerk Maxwell (1831-1879)
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.

Books

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

Amazon logo Lo, Hoi-Kwong, Sandu Popescu, and Tim Spiller. Introduction to Quantum Computation and Information. River Edge, NJ: World Scientific, 1999. ISBN: 9789810233990.
The book is based on a lecture series held at Hewlett-Packard Laboratories, Bristol, UK, November 1996-April 1997.

Amazon logo Nielsen, Michael A., and Isaac L. Chuang. Quantum Computation and Quantum Information. Cambridge, UK: Cambridge University Press, 2000. ISBN: 9780521635035.
This is probably the best of the books intended for scientists and engineers. Chuang, an MIT graduate, is currently on the MIT faculty.

This book, written by a New York Times science writer, is for the general public and may not be technical enough for some readers.

Maxwell's Demon in its many forms has captured the imagination of both scientists and the general public.

Amazon logo Brillouin, Leon. Science and Information Theory. 2nd ed. New York, NY: Dover, 2004. ISBN: 9780486439181.
Topics include Brownian motion, thermal noise, information theory, entropy, and the author's personal view of Maxwell's Demon.

Amazon logo Leff, Harvey S., and Andrew F. Rex. Maxwell's Demon: Entropy, Information, Computing. Princeton, NJ: Princeton University Press, 1991. ISBN: 9780691087276.
General historical discussion with many reprints of original papers but not, regrettably, any of Maxwell's own publications.

Amazon logo von Baeyer, Hans Christian. Maxwell's Demon. New York, NY: Random House, 1998. ISBN: 9780679433422.
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.
