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.

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.
