Gaussian intrinsic entanglement
Ladislav Mišta, Richard Tatham
We introduce a cryptographically motivated quantifier of entanglement in bipartite Gaussian systems called Gaussian intrinsic entanglement (GIE). The GIE is defined as the optimize…

Gaussian intrinsic entanglement: An entanglement quantifier based on secret correlations
Ladislav Mišta, Richard Tatham
Intrinsic entanglement (IE) is a quantity which aims at quantifying bipartite entanglement carried by a quantum state as an optimal amount of the intrinsic information that can be…

Nonexistence of entangled continuous-variable Werner states with positive partial transpose
Daniel McNulty, Richard Tatham, Ladislav Mišta
We address an open question about the existence of entangled continuous-variable (CV) Werner states with positive partial transpose (PPT). We prove that no such state exists by sho…
