TL;DR

This paper investigates how Fisher information can be used to estimate teleported and gained parameters in a non-inertial frame, considering effects of acceleration, entanglement, and initial states.

Contribution

It introduces a method to estimate parameters in non-inertial frames using Fisher information, accounting for acceleration and entanglement effects, with analysis of initial state structures.

Findings

Estimation degree depends on Unruh acceleration and initial state structure.

Classical information teleportation maximizes estimation accuracy.

Fisher information varies with entanglement and approximation methods.

Abstract

We estimate the teleported and the gained parameters by means of Fisher information in a non-inertial frame. The sender and the receiver share an accelerated maximum or partial entangled state. The estimation degree of these parameters depends on Unruh acceleration, the used single mode approximation(within/ beyond), the structure of the initial teleported state, and the entanglement of the initial communication channel. The maximization and minimization estimation degree of the teleported parameters depend on the initial encoded information. The estimation degree of the parameters can be maximized if the partners teleport classical information.
