Entanglement teleportation via a couple of quantum channels in Ising–Heisenberg spin chain model of a heterotrimetallic Fe–Mn–Cu coordination polymer Project supported by the National Natural Science Foundation of China (Grant No. 11274102), the New Century Excellent Talents in University of Ministry of Education of China (Grant No. NCET-11-0960), and the Specialized Research Fund for the Doctoral Program of Higher Education of China (Grant No. 20134208110001). |
The density plot of the average fidelity FA as functions of T and Δ for J1 = J2 = −1: (a) h = 0, (b) h = 0.3. Here the red curve corresponds to FA = 2/3. |
