Measurement-induced disturbance and thermal negativity of qutrit-qubit mixed spin chain
Guofeng Zhang, Yuchen Hou, Ailing Ji
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…
