Weak measurements [1] Pre and Post selection in strong measurements
... These two measurements are strong measurements. We notice that similarly to eq. (1) formalism the TSVF yields maximal information about how the system can affect the environment when interacting with it at time t and that both have the same predictions for the system. The first questions that arises ...
