Three-qubit Thermal Entanglement via Entanglement Swapping on Two-qubit Heisenberg XY chains

Zi Chong Kao, Jezreel Ng, Ye Yeo

In this paper we consider the generation of a three-qubit GHZ-like thermal state by applying the entanglement swapping scheme of Zukowski {\it et al.} [Ann. N. Y. Acad. Sci. {\bf 7…
