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…
Demonstration of quantum controlled teleportation for discrete variables on linear optical devices
Artur Barasiński, Antonín Černoch, Karel Lemr
We report an experimental implementation of tripartite controlled quantum teleportation on the quantum optical devices. The protocol is performed through bi- and tripartite entangl…
Experimental verification of time-order-dependent correlations in three-qubit Greenberger-Horne-Zeilinger-class states
Artur Barasiński, Antonín Černoch, Karel Lemr +1
In this paper, we investigate the genuine three-way nonlocality which is recognized as the strongest form of tripartite correlations. We consider theoretically and experimentally a…
Interplay between strong and weak measurement: Comparison of three experimental approaches to weak value estimation
Jan Roik, Karel Lemr, Antonín Černoch +1
Weak values are traditionally obtained using a weak interaction between the measured system and a pointer state. It has, however, been pointed out that weak coupling can be replace…
Measuring distances in Hilbert space by many-particle interference
Karol Bartkiewicz, Vojtěch Trávníček, Karel Lemr
The measures of distances between points in a Hilbert space are one of the basic theoretical concepts used to characterize properties of a quantum system with respect to some etalo…
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…
