| Sep 1, 2020 at 14:49 | comment | added | user1936752 | I don't understand the part where you say $|\rho - \sigma| = Q+S$. The left hand side is a number while the right hand side is an operator. I don't have a copy of the book but would you mind clarifying this bit so the answer is self-contained? | |
