The reading assignment for today is Chapter 1 in Burd. Once we complete that, and in that same spirit (that is, without necessarily working with matrices directly, by hand, but acknowledging them in Qiskit) we refer to this lecture (and set of exercises) from last year

Recall we had similar exercises posted early first week. Can you try to solve those now? Thanks.
