Objectives
The objective of this course is to introduce the mathematical theory of quantum information processing (a.k.a. quantum computing) at the graduate level. Topics include: basic quantum algorithms (including Shor’s factoring algorithm and Grover’s search algorithm), complexity theory, density matrices and quantum operations on them, distance measures between quantum states, entropy and noiseless coding, error-correcting codes and fault-tolerance, non-locality, and cryptography.

Each project consists of a written component and an oral presentation to the class. It should explain and analyze some topic in quantum information processing, selected with the approval of the instructor. Your presentation should be about 30 minutes in length and your written component is not required to be of any particular length, but around 10 pages would be typical. You should explain the topic in your own words, at a level accessible to your classmates.
Here is a list of project topics to choose from [pdf]. You are also be welcome to pursue a project topic that is not on the list.
