Abstract

AHADPOUR, S.  and  MIRMASOUDI, F.. The pairwise quantum correlations for teleported state via a symmetric multi-qubit system. Rev. mex. fis. [online]. 2019, vol.65, n.4, pp.412-418.  Epub May 06, 2020. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.65.412.

The dynamics of pairwise quantum correlations for teleported state via a symmetric multi-qubit system is investigated. Using the quantum discord, super quantum discord and concurrence to quantify quantum correlations for teleported state, some analytical and numerical results are presented. We compare the dynamical evolutions of quantum correlations and fidelity versus the measurement strength and the number of qubit channel for teleported state via symmetric multi-qubit model. The results show that the 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, this quantum correlations can provide an effective role in quantum teleportation.
