CS 467: Introduction to Quantum Information Processing
Watch a video introduction to this course on YouTube.
General description
Quantum Information Processing (QIP) seeks to exploit the quantum features of nature to provide a qualitatively different and more powerful way of processing information than "classical" physics seems to allow. The course provides students with a basic foundation in the field of quantum information processing (often just called "quantum computing"). Students also explore the fundamental concepts in theoretical computer science and physics, which will allow them to pursue further studies in QIP.
