Characterising the set of deterministic quantum correlations in prepare-and-measure scenarios
Nicola D'Alessandro, Oliver Karlsson, Carles Roch i Carceller
Correlations that do not admit a deterministic explanation are a central feature of quantum theory and a key resource for quantum information processing. Identifying and certifying…
Almost all pure entangled states enable unbounded nonlocality sharing
Anna Steffinlongo, Nicola D'Alessandro, Martin J. Renner
We establish a connection between Hardy's paradox and nonlocality sharing in sequential bipartite scenarios, where each subsystem is measured in turn by a chain of observers. We sh…
Quantum coherence as randomness under classical control
Gabriele Cobucci, Nicola D'Alessandro, Raphael Brinster +3
Quantum states that do not commute exhibit coherence, but only when the device preparing them is assumed to be unaffected by classical parameters inaccessible to the experimenter.…
Semidefinite block-matrix relaxations for computing quantum correlations
Nicola D'Alessandro, Carles Roch i Carceller, Armin Tavakoli
Bounding the correlations predicted by quantum theory is an important challenge in quantum information science. Today's leading approach is semidefinite programming relaxations, bu…
