Abstract

The quantum entanglement of two interacting anisotropic magnetic nanodots was analyzed. The nanodots were shown analytically and numerically to be resonantly dependent on their interaction strength and on differences in their properties. Heisenberg-type exchange interaction characterized by the coupling constant J was used to couple the two dots. Criteria for fabricating and coupling magnetic nanodots so that their low-lying eigenstates can be significantly entangled was provided by the results.
