The ultimate terminal point of the silicon roadmap is the length scale at which classical device physics gives way to quantum mechanics. Upon crossing into this new regime, traditional concepts such as logic levels, transistor switching, and signal restoration loose their usual meaning. In fact, in the quantum domain, the notions of what information is, how algorithms are performed, and how errors are corrected, are fundamentally changed.

Quantum information and quantum computation are new fields which have developed over the past two decades to quantify and utilize the new resources available in systems operating in the quantum regime. These resources can provide non-local behavior through the entanglement of quantum bits (qubits), and a kind of parallelism due to the ability of quantum bits to exist in a superposition of zero and one simultaneously.

I will describe some of the surprising theoretical and experimental results which have been obtained in these fields, including our recent implementation of a five qubit quantum computer at IBM.


Isaac Chuang is a research staff member at the IBM Almaden Research Center, and a consulting professor in E.E. at Stanford University. He received his doctorate in electrical engineering from Stanford, where he was a Hertz Foundation Fellow. As a senior technical associate at AT&T Bell Laboratories (1989-90), Dr. Chuang received wide acclaim for his experimental cosmology work in the laboratory. He has been a visiting researcher at the Fujitsu Parallel Computing Research Center (1992), Nippon Telephone and Telegraph (NTT) Basic Research Laboratory (1994), and the University of California at Santa Barbara's Institute for Theoretical Physics (1996). He was also a post-doctoral fellow at Los Alamos National Laboratory and the University of California at Berkeley. In 1999, MIT Technology Review named Dr. Chuang one of the top 100 young innovators of the year.
