Compound beams for direct experimental comparison of quantum operations
Kishore Thapliyal, Jan Perina, Pavel Pavlicek +1
Compound beams composed of simple experimental blocks (detected in simultaneous detection windows) that form specific quantum-correlated structures are suggested for simulating the…
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…
Experimental hierarchy of the nonclassicality of single-qubit states via potentials for entanglement, steering, and Bell nonlocality
Josef Kadlec, Karol Bartkiewicz, Antonín Černoch +2
Entanglement potentials are a promising way to quantify the nonclassicality of single-mode states. They are defined by the amount of entanglement (expressed by, e.g., the Wootters…
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…
