Hadamard Learning Seminar

Michael Brannan and Nick Priebe, Department of Pure Mathematics, University of Waterloo

"Quantum symmetries of Hadamard Matrices, Revisited (Part 2)"

This is the second of two talks: We will revisit quantum automorphisms of Hadamard matrices, following the preprint of D. Gromada (arxiv:2210.02047v3).  We will compare this with the original definition of Banica-Nicoara introduced in the seminar a few weeks ago, and connect it to the quantum automorphism groups of Hadamard graphs.
