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). |
(a) Magnetic structure of the Ising–Heisenberg spin chain of the heterotrimetallic coordination compounds Fe–Mn–Cu. The green, violet, and orange balls denote Cu2+, Mn2+, and Fe3+ ions, respectively. The dashed lines indicate the Ising coupling, the solid lines represent the Heisenberg coupling, and the dashed box denotes the quantum channel. (b) A schematic drawing of the teleportation of the input state (ρin) via a couple of quantum channels (ρch). The output state of teleportation is denoted as ρout. |
