Explicit formula for the Holevo bound for two-parameter qubit estimation problems
Jun Suzuki (UEC)
Abstract (in Japanese) (See Japanese page) 
(in English) We derive an explicit expression for the Holevo bound for any two-parameter estimation problem of mixed-state qubit models.
The obtained formula depends solely on a given weight matrix and three previously known bounds: The symmetric logarithmic derivative (SLD) Cramer-Rao (CR) bound, the right logarithmic derivative (RLD) CR bound, and the bound for D-invariant models.
We discuss necessary and sufficient conditions for two important cases; the Holevo bound coincides with the RLD CR bound and it does with the SLD CR bound. We show that the Holevo bound for a general model other than these special cases exhibits an unexpected property: The structure of the Holevo bound changes when weight matrix varies.
