Abstract

We study the pairwise quantum correlations for teleported state via a symmetric multi-qubit
system. In the other words, the proposed model is considered as a quantum channel. Using the
quantum discord, super quantum discord and concurrence to quantify quantum correlations for
teleported state, some analytical and numerical results are presented. Moreover, we compare the
dynamical evolutions of quantum correlations and fidelity versus measurement strength and the
number of qubit channel for teleported state via symmetric multi-qubit model. Our main goal
now is to study how we can increase the quantum correlations and the fidelity of the teleported
state in the presence of decoherence. The results show that, measurement strength and the
number of qubit can control the quantum information obtained through the quantum channel.
Therefore, measurement strength can be a good option for measuring exchanged information in
the teleportation process. In addition to, quantum correlations can provide an effective role in
quantum teleportation
