Course description

With the birth of Quantum Mechanics a century ago, our understanding of the physical world has profoundly expanded, and so has our understanding of information. While a classical bit assumes only discrete values, represented by the binary values zero and one, a quantum-mechanical bit or “qubit” can assume a continuum of intermediate states. Quantum Information Theory studies the remarkable properties of this new type of information, ways of processing it, as well as its advantages and limitations.

This course offers a mathematical introduction to Quantum Information Theory. We will start with the fundamentals (such as quantum states, measurements, and entropy) and then discuss some more advanced topics (entanglement theory and quantum communication) and techniques (semidefinite programming and representation theory).

This course will complement Ronald de Wolf’s course on Quantum Computing. Students interested in writing a thesis in quantum information theory are encouraged to follow both courses.

Prerequisites

Familiarity with basic linear algebra and probability theory. Concretely, you should be familiar with the majority of the material in Sections 1.1.2 and 1.2.2 of John Watrous’ textbook (see below). We will briefly remind you of the more difficult bits in class. Prior exposure to the formalism of quantum mechanics or information theory will be very helpful, but not necessary.

Lecture notes

Homework

The next problem set will be posted by Monday, March 25.

Rules about Homework and Exam

The final grade will be determined 40% by the homework grade and 60% by the final exam.

There will be one homework problem set per week, posted on the course homepage by Monday, and you should submit your completed assignment before the lecture the week after (either in class or by email). Assignments will be accepted late only if you have extenuating circumstances (such as sickness or family emergency) and provided you confirm with the lecturer before the deadline.

Your lowest two scores on the problem sets will be ignored (this includes any problem set you did not submit).

Lecture Notes and Literature

Main reference is John Watrous’ textbook “The Theory of Quantum Information” (available online). Watrous’ 2011 lectures notes may also be useful as supplementary reading (see here).

FAQ

Is this the first time this class is offered?

This is the first time this class is offered at the University of Amsterdam. Last year, Michael Walter offered a related course on Symmetry and Quantum Information.

Can this course only be taken by students enrolled in the Master’s of Mathematics?

No! You should be able to take the course as part of the “free choice” component of your Master’s program (in which case you can get credit) or as an additional course (which should show up on your Master’s diploma as well).

Moreover, auditors are very welcome, too, so feel free to drop by to watch a particular lecture if there’s a topic that interests you particularly.

Where can I learn more advanced material?

Attend the QuSoft seminar and write a Master’s thesis at QuSoft!
