Course description: This course covers quantum information theory, quantum algorithms, and quantum error correction.

Class meetings: Monday and Wednesday 2:30-3:55 in 269 Lauritsen.

 

Instructor:
John Preskill, 206 Annenberg, X-6691, email: preskill(at)caltech(dot)edu

Teaching assistant:

Charles Xu, email: cxu3(at)caltech(dot)edu
Office hours: Tuesdays 4:00--5:30pm in 238 Annenberg (during weeks when problems are due)

Lectures and references:
The primary reference for most of the lectures will be these lecture notes (JP). Other useful books are Quantum Computation and Quantum Information by Nielsen and Chuang (NC), Classical and Quantum Computation by Kitaev, Shen, and Vyalyi (KSV), Quantum Computing Since Democritus by Aaronson, and Quantum Information Theory by Wilde.

Other recommended lecture notes: John Watrous, Umesh Vazirani, Andrew Childs, Scott Aaronson

Course outline for winter term:
(Professor Kitaev lectured for the first five weeks of the term.)
Good references on quantum error correction are this review by Gottesman, and this review by Terhal. See also JP Chapter 7.
