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…
