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…
Resource-efficient entanglement detection in high-dimensional states via two-qubit witnesses
Josef Kadlec, Artur Barasiński, Karel Lemr
This paper presents an efficient method for detecting entanglement in high-dimensional two-qudit states by mapping the Hilbert space onto the space of two qubits. This transformati…
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 relative entanglement potentials of single-photon states
Josef Kadlec, Karol Bartkiewicz, Antonín Černoch +2
Entanglement potentials (EPs) enable the characterization and quantification of the nonclassicality of single-mode optical fields by measuring the entanglement generated through be…
Enhancing collective entanglement witnesses through correlation with state purity
Kateřina Jiráková, Antonín Černoch, Artur Barasiński +1
This paper analyzes the adverse impact of white noise on collective quantum measurements and argues that such noise poses a significant obstacle to the otherwise straightforward de…
Unveiling quantum steering by quantum-classical uncertainty complementarity
Kuan-Yi Lee, Jhen-Dong Lin, Karel Lemr +5
One of the remarkable aspects of quantum steering is its ability to violate local uncertainty complementarity relations. In this vein of study, various steering witnesses have been…
