Genuine multipartite entanglement of superpositions
Zhihao Ma, Zhihua Chen, Shao-Ming Fei · Physical Review A · 2014
We investigate how the genuine multipartite entanglement is distributed among the components of superposed states. Analytical lower and upper bounds for the usual multipartite negativity and the genuine multipartite entanglement negativity are derived. These bounds are shown to be tight by detailed examples.
