... can be results of experiments, where O is an operator on the Hilbert space. In particular, an overall phase factor, ψ 7→ ψeic , c ∈ R, does not change the result of the physical measurements. In other words the physical states are normalized L2 functions modulo an overall phase multiple. Again, it i ...

... But the indefinite integral is − 12 exp(−x 2 ) , and so substituting the limits we obtain = λ / 2 = Λ as desired. One could try to rationalize away the annoying factor of 1/2 that appears in this result by arguing that we should restrict attention to only the half of the particles that are traveli ...

Entanglement and Distinguishability of Quantum States
... interpretation is typically related to non-locality. In our talk we will show that entanglement is physically related also with the concept of distinguishability of quantum states. Lets consider two systems differing by a unitary transformation. Can we decide if the two corresponding states are diff ...
