Highly noise resistant multipartite quantum correlations
Wieslaw Laskowski, Tamas Vertesi, Marcin Wiesniak
We analyze robustness of correlations of the -qubit GHZ and Dicke states against white noise admixture. For sufficiently large , the Dicke states (for any number of excitatio…
Multipartite entanglement detection with minimal effort
Lukas Knips, Christian Schwemmer, Nico Klein +2
Certifying entanglement of a multipartite state is generally considered as a demanding task. Since an qubit state is parametrized by real numbers, one might naively e…
Quantum Byzantine Agreement via Hardy correlations and entanglement swapping
Ramij Rahaman, Marcin Wieśniak, Marek Żukowski
We present a device-independent quantum scheme for the {\em Byzantine Generals} problem. The protocol is for three parties. Party is to send two identical one bit messages to p…
Two Copies of the Einstein-Podolsky-Rosen State of Light Lead to Refutation of EPR Ideas
Krzysztof Rosołek, Magdalena Stobińska, Marcin Wieśniak +1
Bell's theorem applies to the normalizable approximations of the original Einstein-Podolsky-Rosen (EPR) state. The constructions of the proof require measurements difficult to perf…
Translating Concepts of State Transfer to Spin-1 Chains
Marcin Wiesniak, Arijit Dutta, Jeonghee Ryu
State transfer is a well-known routine for various systems of spins-. Still, it is not well studied for chains of spins of larger magnitudes. In this contribution we arg…
