Measuring concurrence in qubit Werner states without aligned reference frame
Kateřina Jiráková, Artur Barasiński, Antonín Černoch +2
The genuine concurrence is a standard quantifier of multipartite entanglement, detection and quantification of which still remains a difficult problem from both theoretical and exp…
Experimentally friendly approach towards nonlocal correlations in multisetting N -partite Bell scenarios
Artur Barasiński, Antonín Černoch, Wiesław Laskowski +3
In this work, we study a recently proposed operational measure of nonlocality by Fonseca and Parisio~[Phys. Rev. A 92, 030101(R) (2015)] which describes the probability of violatio…
Demonstration of quantum controlled teleportation for discrete variables on linear optical devices
Artur Barasiński, Antonín Černoch, Karel Lemr
We report an experimental implementation of tripartite controlled quantum teleportation on the quantum optical devices. The protocol is performed through bi- and tripartite entangl…
Experimental verification of time-order-dependent correlations in three-qubit Greenberger-Horne-Zeilinger-class states
Artur Barasiński, Antonín Černoch, Karel Lemr +1
In this paper, we investigate the genuine three-way nonlocality which is recognized as the strongest form of tripartite correlations. We consider theoretically and experimentally a…
Quantum correlations and entanglement in a model comprised of a short chain of nonlinear oscillators
J. K. Kalaga, A. Kowalewska-Kudłaszyk, W. Leoński +1
We discuss a model comprised of a chain of three Kerr-like nonlinear oscillators pumped by two modes of external coherent field. We show that the system can be treated as nonlinear…
