Your example gives OSR where the sum is just 1 term, but for general completely positive maps, you can have more than one term in the sum | |
| Apr 7, 2023 at 16:50 | comment | added | Yaroslav Bulatov | you are right, I was playing around with representations from Watrous "Quantum Information", it's Eq. 2.87 for completely positive map $f$, it seems it should be max and not min | |
