QUANTUM COMMUNICATION VIA HEISENBERG XYZ SYSTEM
The possibility of generating entangled network via Dzyaloshinskii-Moriya interaction is investigated. The entanglement between the different nodes is quantified. This entangled network is employed to send information between different users who are members on this network. The effect of the field strength and the magnetic field parameters on the degree of entanglement of the network and the average fidelity is discussed. We show that by controlling these parameters one can maximize the average fidelity of the teleported state.
