Phys 572.001     Quantum Information Theory       Fall 2014

Syllabus


The syllabus provides a schedule for the course and access to all the web-based material. Click to get a pdf file for lecture notes, special handouts, homework assignments, and solution sets.

Students adopting the graded track will be graded on their performance on the homework assignments; the homework will not be graded, but you should discuss your completed assignment with the instructor by the due date. To receive a grade of CR on the ungraded track, students need only attend the lectures and show interest. There will not be any exams.

Each homework assignment will consist of several problems, some of which will be quite ambitious. The homework problems will be assigned individually, each with its own due date. This allows me more easily to make up problems that occur to me as we go along.

You should consult the syllabus often to keep track of changes and to get access to course material, particularly the homework problems as they are assigned.

I'm pretty confident we can cover the material in the time allotted. We will perhaps seem to be going pretty slowly, but this reflects my general philosophy that it is better to learn a few things well than to be exposed to many things sketchily.
