Complementarity and state estimation
نویسنده
چکیده
The concept of complementarity (or quasi-orthogonality) is extended to POVM's. It is shown in the setting of unconstrained state estimation that the determinant of the mean quadratic error matrix is minimal if the POVM's are complementary (and informationally complete). Several examples of the scheme are given.

Reverse estimation theory, Complementarity between SLD and RLD, and monotone distances
Many problems in quantum information theory can be vied as interconversion between resources. In this talk, we apply this view point to state estimation theory, motivated by the following observations. First, a monotone metric takes value between SLD and RLD Fisher metric. This is quite analogous to the fact that entanglement measures are sandwiched by distillable entanglement and entanglement ...
متن کاملAn Error Estimation for Management Equilibrium Model
In this paper, we extended the result about the error estimation for linear complementarity problem to the extended linear complementarity problem (ELCP) in management equilibrium modeling. More precisely, we first present that the level set of a computable residual function is bounded, and give error estimation in level set. Based on this, we use this residual function to establish a global er...
