Informationally restricted quantum correlations
Armin Tavakoli, Emmanuel Zambrini Cruzeiro, Jonatan Bohr Brask +2
Quantum communication leads to strong correlations, that can outperform classical ones. Complementary to previous works in this area, we investigate correlations in prepare-and-mea…
Does violation of a Bell inequality always imply quantum advantage in a communication complexity problem?
Armin Tavakoli, Marek Żukowski, Časlav Brukner
Quantum correlations which violate a Bell inequality are presumed to power better-than-classical protocols for solving communication complexity problems (CCPs). How general is this…
Experimental Certification of Sustained Entanglement and Nonlocality after Sequential Measurements
Giulio Foletto, Luca Calderaro, Armin Tavakoli +5
Entanglement is a fundamental resource for quantum information science. However, bipartite entanglement is destroyed when one particle is observed via projective (sharp) measuremen…
Constraints on nonlocality in networks from no-signaling and independence
Nicolas Gisin, Jean-Daniel Bancal, Yu Cai +5
Generalising the concept of Bell nonlocality to networks leads to novel forms of correlations, the characterization of which is however challenging. Here we investigate constraints…
Autonomous multipartite entanglement engines
Armin Tavakoli, Géraldine Haack, Nicolas Brunner +1
The generation of genuine multipartite entangled states is challenging in practice. Here we explore a new route to this task, via autonomous entanglement engines which use only inc…
Measurement incompatibility and steering are necessary and sufficient for operational contextuality
Armin Tavakoli, Roope Uola
Contextuality is a signature of operational nonclassicality in the outcome statistics of an experiment. This notion of nonclassicality applies to a breadth of physical phenomena. H…
Sequential random access codes and self-testing of quantum measurement instruments
Karthik Mohan, Armin Tavakoli, Nicolas Brunner
Quantum Random Access Codes (QRACs) are key tools for a variety of protocols in quantum information theory. These are commonly studied in prepare-and-measure scenarios in which a s…
Noise-robust preparation contextuality shared between any number of observers via unsharp measurements
Hammad Anwer, Natalie Wilson, Ralph Silva +3
Multiple observers who independently harvest nonclassical correlations from a single physical system share the system's ability to enable quantum correlations. We show that any num…
