In fact, we argue that it is a property common to a wide range of phase descriptions, including the Pegg-Barnett formalism.engReply to ‘‘Comment on ‘Phase-difference operator’ ’’journal articlehttp://dx.doi.org/10.1103/PhysRevA.51.861http://journals.aps.org/open access535Quantum-theoryÓptica (Física)2209.19 Óptica Física
