The phase distribution is\ncharacterized by the relative entropy--a nonlinear functional of input quantum\nstate. As an explicit example the multiple measurement of quadrature operator\nis interpreted as quantum phase detection achieving the ultimate resolution\npredicted by the Fisher information.",
