Preservation of entanglement in a two-qubit-spin coupled system
arXiv:1108.4981 · doi:10.1016/j.aop.2011.08.004
Abstract
A theoretical scheme to preserve the entanglement in a two-qubit-spin coupled system in the presence of Dzyaloshinskii-Moriya (DM) anisotropic antisymmetric interaction is proposed. Based on a sequence of operations performed periodically on the system, the scheme can preserve the entanglement of the system starting from any initial state with any high precision for any long duration.
