We study the variation of entanglement with distance for a two spin-1/2 system with Dzyaloshinskii-Moriya (DM) interaction, while one of the spins is driven by a time-varing rotating magnetic field and the other one is coupled with a static magnetic field. We show that when we consider the spin-spin coupling coefficient in the form of the Calogero-Moser types, the entanglement can increase with the distance and reach a peak then it decreases for a short distance and will be unchanged for very long distances. So, it is possible to create a significant amount of entanglement between distant qubits, simultaneously avoiding direct interactions between them and single-subsystem addressing.
