Abstract

A statistical parameter estimation theory for quantum pure state models is presented. We first investigate the basic framework of pure state estimation theory and derive quantum counterparts of the Fisher metric. We then formulate a one-parameter estimation theory, based on symmetric logarithmic derivatives, and clarify the differences between pure state models and strictly positive models.
