摘要：

Maximum likelihood estimation of an unknown c-number phaseshift is considered, along the lines established by Shapiro, Shepard and Wong. An input state is exhibited whose reciprocal peak likelihood vanishes, delta-phi --> 0, while its phase-measurement probability density converges, in distribution, to uniform, p(phi/PHI) --> d1/2-pi.
