Abstract
Entanglement is considered to be a key feature of multipartite quantum correlated systems. For instance in [1] entanglement has been shown in all 511 bipartitions of a 10 mode Gaussian state. Beyond bi-partitions, the determination of entanglement for tripartitions or even higher partitions has not been demonstrated in such a complex system. In total, we have 115975 partitions for a 10 mode quantum systems. A recently developed approach can witness entanglement for any partitioning [2]. Thus, it yields a deeper insight into the structure of quantum correlated states.
