摘要

The effects of noisy channels on the quantum Fisher information, channel capacity and non-local information of an accelerated qubit-qutrit system are discussed. Different phenomena are predicted for all these physical quantities, namely sudden/gradual and frozen behaviors. It is shown that the channel strength plays the central role in frozen behavior for all the noisy channels considered. The decay/increase rate depends on which subsystem is accelerated (qubit or qutrit). The frozen areas of these quantities are depicted at different ranges of channel strength and initial input. The maximum/minimum bounds of the estimation degree of the considered quantities depend on the used noisy channel and the dimensions of the accelerated subsystem.
