Objectives
Quantum Information Processing (also known as "quantum computing") seeks to harness the strange power of quantum mechanics to provide a qualitatively different and more powerful way of processing information than "classical" physics seems to allow. The objective of this course is to introduce this multidisciplinary subject at the graduate level.

Topics to be covered
Detailed syllabus: [PDF]
Overview
(timing information is approximate):
   
Introduction to the quantum information framework (3 lectures).
    Quantum algorithms and complexity theory (8 lectures).
    Density matrices and quantum operations on them (3 lectures).
    Distance measures between quantum states (1 lecture).
    Entropy and noiseless coding (1 lecture).
    Error-correcting codes and fault-tolerance (3 lectures).
    Nonlocality (2 lectures).
    ○ Cryptography (3 lectures).

Intended audience
This course is mainly intended for graduate students in CS, C&O or Physics. Other students may take this course with the permission of the instructor.
Prerequisites are MATH 235 or equivalent (e.g. PHYS 364 & 365); STAT 230 or equivalent. Note: this course cannot be taken for credit by students who have taken CO 481 / CS 467 / PHYS 467.

Projects (worth 40% of the final grade)
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 (PDF, PS, and Word are acceptable formats). You should explain the topic in your own words, at a level accessible to your classmates.

Partial list of possible project topics
[ PDF format, Word format ]
Note that you are welcome to pursue a project topic that is not on the list. In any event, you should seek approval from the instructor for your project topic.
