On the existence of fully inseparable biseparable Gaussian states
Olga Leskovjanová, Klára Baksová, Jan ProvaznÃk +2
Genuine multipartite entanglement and full inseparability are two inequivalent quantum resources. Even though all genuinely multipartite entangled states are also fully inseparable…
Experimental verification of multi-copy activation of genuine multipartite entanglement
Robert Stárek, Tim Gollerthan, Olga Leskovjanová +5
A central concept in quantum information processing is genuine multipartite entanglement (GME), a type of correlation beyond biseparability, that is, correlations that cannot be ex…
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…
