For any unitary matrix U of finite size, the following hold: • Given two complex vectors x and y, multiplication by U preserves their inner product; that is, ⟨Ux, Uy⟩ = ⟨x, y⟩. • U is normal (). • U is diagonalizable; that is, U is unitarily similar to a diagonal matrix, as a consequence of the spectral theorem. Thus, U has a decomposition of the form where V is u… For any unitary matrix U of finite size, the following hold: • Given two complex vectors x and y, multiplication by U preserves their inner product; that is, ⟨Ux, Uy⟩ = ⟨x, y⟩. • U is normal (). • U is diagonalizable; that is, U is unitarily similar to a diagonal matrix, as a consequence of the spectral theorem. Thus, U has a decomposition of the form where V is unitary, and D is diagonal and unitary. http://www.mphys7.ipb.ac.rs/slides/Naraghi.pdf
