In quantum mechanics, systems are described by wavefunctions, which contain in them all the physically accessible information about a system. These wavefunctions exist in Hilbert spaces, infinite-dimensional vector spaces spanned by orthogonal basis states. The choice of basis corresponds to the choice of the…
