Simultaneous communication of relevant parameters

Abstract

The aim of this work is to investigate bidirectional quantum teleportation (BQT) of information, where a Bell state is considered as the quantum channel of the teleportation process. We consider that the Bell state is distributed by a noisy amplitude damping channel. We analyze the behavior of quantum Fisher information(QFI), which provides a tool to quantify the efficiency of bidirectional teleportation. Our results show that by using the weak measurement technique it is possible to mitigate the effect of the noise and enhance the bidirectional teleportation of relevant parameters.
