Berry The problem of measuring a time-varying phase, even when the statistics of the variation is known, is considerably harder than that of measuring a constant phase. In particular, the usual bounds on accuracy, such as the 1 / ( 4 n ¯ ) standard quantum limit with coherent states, do not apply. Here, by rest... [Phys. Rev. A 97, 042334] Published Mon Apr 23, 2018
