## CS C191. Quantum Information Science and Technology

### Description

Catalog Description: (3 units) Three hours of lecture/discussion per week. This multidisciplinary course provides an introduction to fundamental conceptual aspects of quantum mechanics from a computational and informational theoretic perspective, as well as physical implementations and technological applications of quantum information science. Basic sections of quantum algorithms, complexity, and cryptography, will be touched upon, as well as pertinent physical realizations from nanoscale science and engineering. Also listed as Physics C191 and Chemistry C191.
