Asymptotic estimation theory for a finite dimensional pure state model
The author studies the optimization of measurement for n copies of pure states. The asymptotic efficiency of the optimal measurement is calculated in the large deviation sense.
متن کاملAsymptotic Attainment for Quantum Relative Entropy
It was proved that quantum relative entropy D(k) is attained by a certain sequence of measurements which is independent of. This formula is thought to be important for the quantum asymptotic detection and the quantum asymptotic estimation. To know the quantum asymptotic estimation, see [13]. The constructions of these applications are, however, left for future study. Acknowledgments I wish to t...
متن کاملساختار فاز میدانهای پیمانهای شبکهای دو بعدی U(N) با کنش مختلط
We study the phase structure of two dimensional pure lattice gauge theory with a Chern term. The symmetry groups are non-Abelian, finite and disconnected sub-groups of SU(3). Since the action is imaginary it introduces a rich phase structure compared to the originally trivial two dimensional pure gauge theory. The Z3 group is the center of these groups and the result shows that if we use one ...
متن کاملConsistency and Asymptotic Normality of Sieve Estimators Under Weak and Verifiable Conditions
This paper considers sieve estimation of semi-nonparametric (SNP) models with an unknown density function as non-Euclidean parameter, next to a finite-dimensional parameter vector. The density function involved is modeled via an infinite series expansion, so that the actual parameter space is infinite-dimensional. It will be shown that under weak and verifiable conditions the sieve estimators o...
متن کاملDevelopment of a Robust Observer for General Form Nonlinear System: Theory, Design and Implementation
The problem of observer design for nonlinear systems has got great attention in the recent literature. The nonlinear observer has been a topic of interest in control theory. In this research, a modified robust sliding-mode observer (SMO) is designed to accurately estimate the state variables of nonlinear systems in the presence of disturbances and model uncertainties. The observer has a simple ...
