M. A. Nielsen and I. L. Chuang, "Quantum Computation and Quantum Information" (optional)

The main subjects of this advanced graduate course are quantum information, quantum computation, and quantum advantage over classical information processing. While basic knowledge about quantum mechanics and related mathematics like linear algebra is assumed, the course will be taught in a selfcontained manner. We adopt modern pedagogy of active learning and engagement in the class. In particular, students are encouraged to educate and peerreview each other, so that they can also learn valuable skills as researchers to explain and communicate well.
The course has two objectives. One is to enlighten the basic concepts of quantum information, which are expected to be useful regardless of research fields everyone chooses. The other is to help preparing the ground to work in quantum information if one is interested in contributing to its research frontiers. It is expected that comprehensive understanding is obtained, when another graduate course PHYC 572 "Quantum Information Theory," in Spring 2017 was taken together. However, even if one has missed the prequel, it would be still possible to follow the lectures by reading the Chapter 2 of the textbook by Nielsen and Chuang supplementarily. There is a timely introduction to the subject, "Why now is the right time to study quantum computing," written by Harrow particularly for students of computer science department.
Students adopting the graded track will be graded on their attendance and performance on the assignments and projects. To receive a grade of CR on the ungraded track, students need to attend the lectures and show interest. Students who plan to work in quantum information or relevant research fields are highly encouraged to be in the graded track.
