Quantum Computation

2018

**Go to home page for
Ph219/CS219 in past years.**

**Course description: **This course
covers quantum information theory, quantum algorithms, quantum error
correction, topological quantum computing, quantum Shannon theory, and some
special topics.

**Class meetings**:
Monday and Wednesday 2:30-3:55 in 103 Downs.

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

Teaching assistant:

Eric Morgan, email: eric(at)caltech(dot)edu

Office hours: TBA

**Lectures and references:
**The primary reference for most of the lectures will be these lecture
notes (JP). Other useful books are

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

The fall term focused on quantum algorithms, and was taught by Professor Kitaev.

**Course outline for winter term:
**The main topics will be quantum error correction (JP Chapter 7),
fault-tolerant quantum computing, and topological quantum computing (JP Chapter
9).

Other good references on quantum error correction are this review by Gottesman, and this review by Terhal.

lecture notes on toric code recovery,
fault-tolerant recovery, and fault-tolerant gates

Lecture 1 (Jan 4): The Knill-Laflamme quantum error
correction conditions

**Course outline for spring term:
**Professor Kitaev will teach the first half
of this term. The main topic will be connections between quantum information
and black holes.

For the second half of the term, the main topic will be quantum Shannon
theory (JP Chapter 10). If time allows, we’ll cover an additional topic at the
end of term --- perhaps quantum simulation of physical systems.

**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.
