Excerpt
Excerpt: Quantum Information Science (QIS) is an emerging field with the potential to cause revolutionary advances in fields of science and engineering involving computation, communication, precision measurement, and fundamental quantum science. The roots of this field go back about twenty years, when pioneers such as Charles Bennett, Paul Benioff, Richard Feynman, and others began thinking about the implications of combining quantum mechanics with the classical Turing computing machine. The field of QIS began an explosive growth in the early to mid 1990’s as a consequence of several simultaneous stimuli: Peter Shor demonstrated that a quantum computer could factor very large numbers super-efficiently. The semiconductor industry realized that the improvement of computers according to Moore’s law would all too soon reach the quantum limit, requiring radical changes in technology. Developments in the physical sciences produced trapped atomic ions, advanced optical cavities, quantum dots, and many other advances that made it possible to contemplate the construction of workable quantum logic devices. Furthermore, the need for secure communications drove the investigations of quantum communication schemes that would be tamper proof.
