AB - We investigate the dynamics of quantum correlations between the quantum  annealing processor nodes. The quantum annealing processor is simulated by  spin-chain model. It is assumed that system started from the thermal state.  The Hamiltonian of the system is mathematically designed and analytically  solved. The properties of the system are investigated. Negativity is used to  investigate the dynamics of quantum correlation between the system nodes.  The effect of the system parameters (spin-orbit coupling, coupling constant,  and bias parameter) on the dynamics of negativity is explored. Results  showed that the coupling constant had a great effect in the dynamics of the  quantum correlation.
