... Since no physical property can depend upon phase, we say that quantum mechanics is invariant, or symmetric, with respect to changes in overall phase. Usually, when we think of symmetry, we think of actions in everyday space (a sphere is rotationally symmetric). In this case, though, the symmetry is ...
