The pairwise quantum correlations for teleported state via a symmetric multi-qubit system

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
