Abstract
Quantum correlation in two-qubit spin models is investigated by use of measurement-induced disturbance [S. Luo, Phys. Rev. A, 77 (2008) 022301]. Its dependences on external magnetic field, spin–spin coupling, and Dzyaloshinski–Moriya (DM) interactions are presented in detail. We also compare measurement-induced disturbance and thermal entanglement in spin models and illustrate their different characteristics.
Research highlights► Quantum correlation (QC) is quantified by measurement-induced disturbance. ► The effects of coupling parameters on QC and thermal concurrence (TC) are presented. ► We compare QC with TC in spin models and illustrate their different characteristics.
