Measurement-induced disturbance and thermal negativity of qutrit-qubit mixed spin chain
arXiv:1103.0085 · doi:10.1016/j.ssc.2011.02.032
Abstract
We investigate the quantum correlation in a qutrit-qubit mixed spin chain based on measurement-induced disturbance (MID) [S. Luo, Phys. Rev. A, 77, (2008) 022301]. We also compare MID and thermal entanglement measured by negativity and illustrate their different characteristics.
