Asymptotic Quantum Estimation Theory for the Thermal States FamilyConcerning state estimation, we will compare two cases. In one case we cannot use the quantum correlations between samples. In the other case, we can use them. In addition, under the later case, we will propose a method which simultaneously measures the complex amplitude and the expected photon number for the thermal states.

The Asymptotic Efficiency of the Consistent Estimator, Berry-Uhlmann’s Curvature, and Quantum InformIt is pointed out that Berry-Uhlmann’s parallelism plays key role in the first order asymptotic theory of quantum statistical estimation, and that the parallelism is closely related to Nagaoka’s quantum information geometry, which is already successfully applied to quantum estimation theory.

Generalised Measurements, Retrodiction and State ManipulationWe develop and discuss noveltypes of generalisedquantum measurement. The associated non-unitary time evolution enables the manipulation of quantum states in ways that are not achievable by unitary operations. Particular emphasis is given to quantum optical realisations.
