Multi-copy activation of genuine multipartite entanglement in continuous-variable systems
Klára Baksová, Olga Leskovjanová, Ladislav Mišta +2
Multi-copy activation of genuine multipartite entanglement (GME) is a phenomenon whereby multiple copies of biseparable but fully inseparable states can exhibit GME. This was shown…
