How to prove the "damage lemma" for gentle measurements?

Let $\rho$ be a mixed state. For all $i \in [m]$, let $S_i$ be quantum operation, which is a two-outcome POVM measurement, and "accept" a state $\sigma$ with probability $tr(S_i(\sigma))$ ...

Kraus Operators for Weak Measurments

I have system which has states two spin states and an optically excited states. Everytime optically excited states relaxes, a photon is emitted, which I can detect a fraction of. If I simulatenously ...
