WebTheorem 1.1 (Gleason). Let H be separable and of dimension unequal to 2. Then every Gleason measure arises from precisely one positive self-adjoint operator, A, of trace 1 in … WebThe Gleason theorem allows us to assign probabilities to these events. The Gleason theorem [ 171] also shows that the Born rule for the probability of obtaining a specific outcome of a given measurement follows naturally from the structure formed by the lattice of events in a real or complex Hilbert space.
