Entanglement generation in a two-body Schrödinger--Newton model
Marcin Płodzień, Julia Osęka-Lenart, Maciej Lewenstein +1
The Schrödinger--Newton (SN) equation provides a semiclassical framework for the evolution of self-gravitating of massive quantum systems. We propose a two-body Schrödinger--Newton…
Two instances of random access code in the quantum regime
Nitica Sakharwade, Michał Studziński, Michał Eckstein +1
We consider two classes of quantum generalisations of Random Access Code (RAC) and study lower bounds for probabilities of success for such tasks. It provides a useful framework fo…
Quantum Optimal Transport
Sam Cole, Michał Eckstein, Shmuel Friedland +1
We analyze a quantum version of the Monge--Kantorovich optimal transport problem. The quantum transport cost related to a Hermitian cost matrix is minimized over the set of all…
Probing the limits of quantum theory with quantum information at subnuclear scales
Michał Eckstein, Paweł Horodecki
Modern quantum engineering techniques enabled successful foundational tests of quantum mechanics. Yet, the universal validity of quantum postulates is an open question. Here we pro…
Quantum Monge-Kantorovich problem and transport distance between density matrices
Shmuel Friedland, Michał Eckstein, Sam Cole +1
A quantum version of the Monge--Kantorovich optimal transport problem is analyzed. The transport cost is minimized over the set of all bipartite coupling states , such that…
Operational causality in spacetime
Michał Eckstein, Paweł Horodecki, Ryszard Horodecki +1
The no-signalling principle preventing superluminal communication is a limiting paradigm for physical theories. Within the information-theoretic framework it is commonly understood…
