The first few weeks of this course will consist of introduction to classical and quantum error correction through lectures by the instructors. After the introduction is completed, we will transition to the seminar part of the course where students will be studying and presenting recent advancements in quantum error correction. The main focus would be on topological codes like the surface and toric codes, and on good quantum codes like the recently developed quantum LDPC codes.
Students can register for either:
Students will be expected to fully participate in classroom discussions. Class time will be focused on:
Each paper presentation will be 20min followed by 10-15min of QnA. The presenter's goal should be to teach the audience about the concepts presented in the paper, why are they valuable, how they might be applied, etc. The 10-15min QnA would be managed by the instructors, who will also try to help with the thornier questions.
This course will be executed together with similar concurrent gatherings at partner universities at the NSF Center for Quantum Networks.
Upon completion of this course, it is expected that students will be able to:
A list of general Quantum Information textbooks is made available and a list of papers for each week will be provided in advance.
We will aim to cover the following topics (numbers in parentheses indicate approximate number of 120-minute lectures for each topic):

Non-local participants from the partner institutions will join us over video conference through Zoom.
