Abstract
We discuss generation and measurement strategies for maximum-likelihood est imation of small phase shifts. We demonstrate that optimal encoding of smal l phase shifts and optimal measurements of small phase shifts require diffe rent states. We also show that states with identical phase resolution may h ave rather different Pegg-Barnett phase distributions. Hence, the connectio n between phase distribution and quantum phase resolution is rather weak.
