Svetlichny’s approach to detecting genuine multipartite entanglement in arbitrarily-high-dimensional systems by a Bell-type inequality
Dong-Ling Deng, Zi-Sui Zhou, Jing‐Ling Chen · Physical Review A · 2009
Based on the assumption of partial separability, we derive Bell-type inequalities for $N$ $d$-dimensional (qudit) systems, which can detect experimentally genuine multipartite entanglement that cannot be reduced to mixtures of states in which a smaller number of particles are entangled. We also introduce the concept ``resolution'' to measure the strength of these inequalities to distinguish full entanglement from partial entanglement when white noise is added to the system.
