On the problem of entity matching and its application in automated settlement of receivables
Lukasz Czekaj, Tomasz Biegus, Robert Kitlowski +7
This paper covers automated settlement of receivables in non-governmental organizations. We tackle the problem with entity matching techniques. We consider setup, where base algori…
Correlations constrained by composite measurements
John H. Selby, Ana Belén Sainz, Victor Magron +2
How to understand the set of correlations admissible in nature is one outstanding open problem in the core of the foundations of quantum theory. Here we take a complementary viewpo…
Operational foundations of complementarity and uncertainty relations
Debashis Saha, Michał Oszmaniec, Łukasz Czekaj +2
The so-called preparation uncertainty can be understood in purely operational terms. Namely, it occurs when for some pair of observables, there is no preparation, for which they bo…
Bell measurement rules out supraquantum correlations
Łukasz Czekaj, Michał Horodecki, Tomasz Tylec
The so called bipartite non-signaling boxes are systems whose statistics is constrained solely by the principle of no instantaneous signaling between distant locations. Such system…
Information Content of Systems as a Physical Principle
L. Czekaj, M. Horodecki, P. Horodecki +1
To explain conceptual gap between classical/quantum and other, hypothetical descriptions of world, several principles has been proposed. So far, all these principles have not expli…
Universal scheme for violation of local realism from quantum advantage in one-way communication complexity
L. Czekaj, A. Grudka, M. Horodecki +2
We consider relations between communication complexity problems and detecting correlations (violating local realism) with no local hidden variable model. We show first universal eq…
Directed percolation effects emerging from superadditivity of quantum networks
L. Czekaj, R. W. Chhajlany, P. Horodecki
Entanglement indcued non--additivity of classical communication capacity in networks consisting of quantum channels is considered. Communication lattices consisiting of butterfly-t…
Nonadditivity effects in classical capacities of quantum multiple-access channels
Lukasz Czekaj, Pawel Horodecki
We study classical capacities of quantum multi-access channels in geometric terms revealing breaking of additivity of Holevo-like capacity. This effect is purely quantum since, as…
