The extent to which a given wave function, ψ, is entangled is measured by minimizing the norm of ψ minus all possible unentangled functions. This measure is given by the largest eigenvalue of ψ † ψ, considered as an operator. Entanglement was considered by Schrödinger to be the essence of quantum behavior. 1 It is the central concept in the EPR paradox and… CONTINUE READING
