Abstract
We explore the three-particle spin model of an particle (e.g., an electron) interacting with two spin-coupled particles with exchange coupling and magnetic anisotropy. We show that in the case of particles, the coupled particle entanglement states can be prepared, controlled, and read by the particle. We also find that for particular resonance conditions of the magnetic anisotropy strength and exchange coupling strength , the entanglement state-switching behavior is maximized and is robust against a range of anisotropic application of the exchange coupling.
