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…
Quantifying nonclassicality of vacuum-one-photon superpositions via potentials for Bell nonlocality, quantum steering, and entanglement
Adam Miranowicz, Josef Kadlec, Karol Bartkiewicz +4
Entanglement potentials are popular measures of the nonclassicality of single-mode optical fields. These potentials are defined by the amount of entanglement (measured by, e.g., th…
Sensitivity versus selectivity in entanglement detection via collective witnesses
Vojtěch Trávníček, Jan Roik, Karol Bartkiewicz +3
In this paper, we present a supervised learning technique that utilizes artificial neural networks to design new collective entanglement witnesses for two-qubit and qubit-qutrit sy…
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…
Direct method for measuring and witnessing quantum entanglement of arbitrary two-qubit states through Hong-Ou-Mandel interference
Karol Bartkiewicz, Grzegorz Chimczak, Karel Lemr
We describe a direct method for experimental determination of the negativity of an arbitrary two-qubit state with 11 measurements performed on multiple copies of the two-qubit syst…
Bell nonlocality and fully-entangled fraction measured in an entanglement-swapping device without quantum state tomography
Karol Bartkiewicz, Karel Lemr, Antonín Černoch +1
We demonstrate an efficient experimental procedure based on entanglement swapping to determine the Bell nonlocality measure of Horodecki et al. [Phys. Lett. A 200, 340 (1995)] and…
