Abstract
The possibility of generating a multi-hops network between different entangled nodes (qubits) via spin Dipolar interaction is examined. The negativity, tangle and the non-local coherent advantage are used as quantifiers of the generated quantum correlations. The phenomena of the sudden death/birth is displayed for the entangled two nodes, while the sudden changes phenomena (increasing/ decreasing) is depicted for all entangled three nodes. The amount of correlations between the different nodes depend on the initial network settings, where the largest amount is predicted if the network is initially conducted via maximum entangled nodes. The generated quantum correlations between each three nodes are more robust than those generated between two nodes. For the generated entangled two nodes, the direction of the interaction and its strength have a remarkable effect on the correlation behavior, while they has a slightly effect on the correlation of the three nodes.
