Adaptive Negativity Estimation via Collective Measurements
Martin Zeman, Vojtěch Trávníček, Antonín Černoch +2
This paper explores an efficient method for entanglement quantification in two-qubit and qubit-qutrit quantum systems based upon the framework of collective measurements in conjunc…
Machine classification of quantum correlations for entanglement distribution networks
Jan Soubusta, Antonín Černoch, Karel Lemr
The paper suggest employing machine learning for resource-efficient classification of quantum correlations in entanglement distribution networks. Specifically, artificial neural ne…
Experimental hierarchy of two-qubit quantum correlations without state tomography
Shilan Abo, Jan Soubusta, Kateřina Jiráková +4
A Werner state, which is the singlet Bell state affected by white noise, is a prototype example of states, which can reveal a hierarchy of quantum entanglement, steering, and Bell…
Compound twin beams without the need of genuine photon-number-resolving detection
Jan Perina, Antonin Cernoch, Jan Soubusta
The scheme for building stronger multi-mode twin beams from a greater number of identical twin beams sufficiently weak so that single-photon sensitive on/off detectors suffice in t…
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…
