Entanglement purification for arbitrary multipartite high-dimensional Greenberger-Horne-Zeilinger state

Yu-Qing Kong, Jia-Ye Liu, Hui-Hui Kong +1

High-dimensional qudit (i.e., $d$-level or $d$-state) systems outperform two-dimensional qubit (i.e., 2-level or 2-state) systems in some quantum information processing tasks. We e…
