Abstract

In this article, we investigate the non-unitary dynamics of a two-qubit system under the action of local non-Hermitian operation from the perspectives of quantum correlations. The correlations are quantified by entanglement, maximal Bell function and different versions of measurement-induced nonlocality (MIN). The analysis is carried out for different initial conditions. We show the advantages of MIN in capturing the nonlocal aspects of the mixed quantum states over the entanglement and Bell function. Interestingly, by proper tuning of the system’s parameter, one can observe the stationary quantum correlations under this non-Hermitian circumstance which have potential applications in quantum information processing and quantum computation.
