Office hours: Thursday 1:30-2:30pm and more times TBD, Room 6-318
Part-time TA: TBD.
This is a third class in the MIT QIS sequence, following 8.370 and 8.371. It ran before in Fall 2020 [as 8.S372/18.S996], in Fall 2022, and in Fall 2024.
Psets and lecture notes will be made public. Registered students (including listeners) can access the canvas site and Piazza discussion boards. Any content only for registered students (such as pset solutions) will be labeled by the 
icon.
This is a third course in quantum information and computing theory, focused on special topics that may change from year to year. This year the focus is on quantum information theory, both understanding the core theory of the field, as well as application to physics.
The first part of the course will introduce the main questions and tools of quantum information theory, such as entropies, capacities, hypothesis testing, decoupling, random states and unitaries, symmetry, and entanglement. The second part will apply these tools, along with those from quantum complexity theory and error correction, to questions in many-body physics.
