@inproceedings{Gurkan2008TwoQE, title={Two Qubit Entanglement in Magnetic Chains with DM Antisymmetric Anisotropic Exchange Interaction}, author={Zeynep Nilhan Gurkan and Oktay K. Pashaev}, year={2008} }

In the present paper an influence of the anisotropic antisymmetric exchange interaction, the Dzialoshinskii-Moriya (DM) interaction, on entanglement of two qubits in various magnetic spin models, including the pure DM model and the most general XY Z model are studied. We find that the time evolution generated by DM interaction can implement the SWAP gate and discuss realistic quasi-one-dimensional magnets where it can be realized. It is shown that inclusion of the DM interaction to any… Expand
