Physical model for the generation of ideal resources in multipartite quantum networking
arXiv:1003.2171 · doi:10.1103/PhysRevA.82.030302
Abstract
We propose a physical model for generating multipartite entangled states of spin- particles that have important applications in distributed quantum information processing. Our protocol is based on a process where mobile spins induce the interaction among remote scattering centers. As such, a major advantage lies on the management of stationary and well separated spins. Among the generable states, there is a class of -qubit singlets allowing for optimal quantum telecloning in a scalable and controllable way. We also show how to prepare Aharonov, W and Greenberger-Horne-Zeilinger states.
