Error tradeoff relation for estimating the unitary-shift parameter of a relativistic spin-1/2 particle
Shin Funada, Jun Suzuki
The purpose of this paper is to discuss the existence of a nontrivial tradeoff relation for estimating two unitary-shift parameters in a relativistic spin-1/2 system. It is shown t…
Effect of Wigner rotation on estimating unitary-shift parameter of relativistic spin-1/2 particle
Shin Funada, Jun Suzuki
We obtain the accuracy limit for estimating the expectation value of the position of a relativistic particle for an observer moving along one direction at a constant velocity. We u…
Error trade-off relations for two-parameter unitary model with commuting generators
Shin Funada, Jun Suzuki
We investigate whether a trade-off relation between the diagonal elements of the mean square error matrix exists for the two-parameter unitary models with mutually commuting genera…
Uncertainty relation for the position of an electron in a uniform magnetic field from quantum estimation theory
Shin Funada, Jun Suzuki
We investigate the uncertainty relation for estimating the position of one electron in a uniform magnetic field in the framework of the quantum estimation theory. Two kinds of mome…
