Svetlichny's approach to detecting genuine multipartite entanglement in arbitrarily-high-dimensional systems by a Bell-type inequality

摘要

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.
