Quantum survival in hybrid pursuit dynamics - a lion chasing a lamb problem
P. Held, İ. Yalçınkaya, F. Pegoraro +10
Measurement and classical randomness usually degrade coherence; controlling where and when a subsystem is monitored can instead make them a tunable resource. We introduce a photoni…
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…
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…
Experimental hierarchy and optimal robustness of quantum correlations of two-qubit states with controllable white noise
Kateřina Jiráková, Antonín Černoch, Karel Lemr +2
We demonstrate a hierarchy of various classes of quantum correlations on experimentally prepared two-qubit Werner-like states with controllable white noise. Werner states, which ar…
Systematic errors in tokamak magnetic equilibrium reconstruction: a study of EFIT++ at tokamak COMPASS
K. Jirakova, O. Kovanda, J. Adamek +2
Uncertainties and errors in magnetic equilibrium reconstructions are a wide-spread problem in interpreting experimental data measured in the tokamak edge. This study demonstrates e…
Experimental hybrid quantum-classical reinforcement learning by boson sampling: how to train a quantum cloner
Jan Jašek, Kateřina Jiráková, Karol Bartkiewicz +3
We report on experimental implementation of a machine-learned quantum gate driven by a classical control. The gate learns optimal phase-covariant cloning in a reinforcement learnin…
Experimental kernel-based quantum machine learning in finite feature space
Karol Bartkiewicz, Clemens Gneiting, Antonín Černoch +3
We implement an all-optical setup demonstrating kernel-based quantum machine learning for two-dimensional classification problems. In this hybrid approach, kernel evaluations are o…
Experimentally attacking quantum money schemes based on quantum retrieval games
Kateřina Jiráková, Karol Bartkiewicz, Antonín Černoch +1
The concept of quantum money (QM) was proposed by Wiesner in the 1970s. Its main advantage is that every attempt to copy QM unavoidably leads to imperfect counterfeits. In the Wies…
Beam tests of an integrated prototype of the ATLAS Forward Proton detector
J. Lange, L. Adamczyk, G. Avoni +24
The ATLAS Forward Proton (AFP) detector is intended to measure protons scattered at small angles from the ATLAS interaction point. To this end, a combination of 3D Silicon pixel tr…
