This is typically taken as an axiom or basic postulate of quantum mechanics, while generalizations of or departures ...
Definition 2. A unitary operator is a bounded linear operator U : H → H on a Hilbert space H for which the following hold: U is surjective, and. U preserves the inner product of the Hilbert space, H. In other words, for all vectors x and y in H we have: U x , U y H = x , y H . {\displaystyle \langle Ux,Uy\rangle _ {H}=\langle x,y\rangle _ {H}.}
