CREATION OF STABLE MULTIPARTITE ENTANGLED STATES IN SPIN CHAINS WITH DEFECTS

    https://doi.org/10.1142/S021974990600202XCited by:3 (Source: Crossref)

    We show how defects in a spin chain described by the XXZ model may be used to generate entangled states, such as Bell and W states, and how to maintain them with high fidelity. We also discuss, in the presence of several excitations, how the anisotropy of the system may be combined with defects to effectively assist in the creation of the desired states.
