Quantum Information Geometry and Quantum Estimation,nknown state parameterized by a continuous variable .. It is a remarkable property of quantum mechanics that a measurement inevitably leads to the state reduction. Therefore, when one performs a measurement for state estimation, it is necessary to choose the measurement that extracts as much informa

Quantum Measurements and State Reduction,stical phenomenon because of the lack of proper understanding. As a result, the formalism for the state reduction is often somewhat inadequately presented. However, as will be explained in Sect.?., the state reduction due to a measurement follows automatically from the formulation of quantum mechani

Entanglement and Locality Restrictions,-specific correlation called entanglement. It is believed that this type of correlation does not exist in macroscopic objects. Entanglement can be used to produce nonlocal phenomena. States possessing such correlations are called entangled states (or states that possess entanglement). A state on a b
