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 fall term:
Topics covered in the tall will include density operators, quantum operations, quantum entanglement, quantum circuits, and quantum algorithms.

Lecture 1 (Oct 1): Introduction (JP Chapter 1).
See also: Quantum computing and the entanglement frontier, and Quantum computing in the NISQ era and beyond.
Video: Canadian Summer School on Quantum Information Lecture 1, Lecture 2.
Lecture 2 (Oct 3): Density operators (JP Chapter 2). Lecture by Victor Albert.
Lecture 3 (Oct 8): Convexity, HJW theorem, generalized measurements (JP Chapter 3)
Lecture 4 (Oct 10): Operations, Choi-Jamiolkowski isomorphism (JP Chapter 3)

Homework assignments: 
All students taking the course for credit are required to do the homework.  Unless otherwise announced, homework will be due on Thursday at 5pm.

Homework should be handed into the box outside of the Ann 232 by the due date, or emailed to Tian <twang3@caltech.edu> if you type it up. Please use a large font or write legibly.

You may receive partial credit if you describe a thoughtful approach to the problem, even if you are unable to solve it completely.

If you have questions, you may post them on Moodle or email them to Tian. Problem solutions will be posted on Moodle.
