. In 1976, he joined the United States Army Research Laboratory (then called the Harry Diamond Laboratory). From 1986 to 1995, he technically directed three major programs for the Office of Innovative Science and Technology of the Strategic Defense Initiative Organization, involving nation-wide research on high-power microwave source development, sensors for interactive discrimination, and electromagnetic missiles and directed energy concepts. Since 1995, he has been performing research on quantum computing and quantum cryptography.

Quantum field theory
Quantum field theory provides a theoretical framework for constructing quantum mechanical models of systems classically parametrized by an infinite number of dynamical degrees of freedom, that is, fields and many-body systems. It is the natural and quantitative language of particle physics and...

Quantum information
In quantum mechanics, quantum information is physical information that is held in the "state" of a quantum system. The most popular unit of quantum information is the qubit, a two-level quantum system...

Education
In 1958, he graduated from Queen Anne High School, Seattle, Washington. He received his BS in physicsPhysics
Physics is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.Physics is one of the oldest academic...
