WebFeb 15, 2015 · Gleason's Theorem states that any probability measure on the projection structure, , of the matrix algebra , , of all complex n by n matrices, extends to a positive linear functional on [13]. Loosely speaking, it says that any quantum probability measure has its expectation value (integral). WebDec 12, 2024 · Gleason's theorem (GT) says that any measure on the space of states that obeys the rules of the probability calculus is given by the Born rule for some state. This …
