Genuine multipartite entanglement of quantum states in the multiple-copy scenario
C Palazuelos, JI De Vicente - Quantum, 2022 - quantum-journal.org
Genuine multipartite entanglement (GME) is considered a powerful form of entanglement
since it corresponds to those states that are not biseparable, ie a mixture of partially …
