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…
Observing High-dimensional Bell Inequality Violations using Multi-Outcome Spectral Measurements
Kiki Dekkers, Laura Serino, Nicola DAlessandro +5
Violation of Bell inequalities is an essential requirement for many quantum information and communication protocols. In high-dimensional systems, Bell inequality tests face the cha…
Observation of Genuine High-dimensional Multi-partite Non-locality in Entangled Photon States
Xiao-Min Hu, Cen-Xiao Huang, Nicola d'Alessandro +10
Quantum information science has leaped forward with the exploration of high-dimensional quantum systems, offering greater potential than traditional qubits in quantum communication…
Semidefinite relaxations for high-dimensional entanglement in the steering scenario
Nicola D'Alessandro, Carles Roch i Carceller, Armin Tavakoli
We introduce semidefinite programming hierarchies for benchmarking relevant entanglement properties in the high-dimensional steering scenario. Firstly, we provide a general method…
Imprecision plateaus in quantum steering
Elna Svegborn, Nicola d'Alessandro, Otfried Gühne +1
We study tests of quantum steering in which the trusted party does not have perfect control of their measurements. We report on steering inequalities that remain unaffected when in…
