Minimal criteria for continuous-variable genuine multipartite entanglement
Olga Leskovjanová, Ladislav Mišta
We derive a set of genuine multi-mode entanglement criteria for second moments of the quadrature operators. The criteria have a common form of the uncertainty relation between sums…

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…
