Contextuality with vanishing coherence and maximal robustness to dephasing
Vinicius P. Rossi, David Schmid, John H. Selby +1
Generalized contextuality is a resource for a wide range of communication and information processing protocols. However, contextuality is not possible without coherence, and so can…
The resource theory of nonclassicality of channel assemblages
Beata Zjawin, David Schmid, Matty J. Hoban +1
When two parties, Alice and Bob, share correlated quantum systems and Alice performs local measurements, Alice's updated description of Bob's state can provide evidence of nonclass…
A hierarchy of semidefinite programs for generalised Einstein-Podolsky-Rosen scenarios
Matty J. Hoban, Tom Drescher, Ana Belén Sainz
Correlations in Einstein-Podolsky-Rosen (EPR) scenarios, captured by \textit{assemblages} of unnormalised quantum states, have recently caught the attention of the community, both…
Simulating all multipartite non-signalling channels via quasiprobabilistic mixtures of local channels in generalised probabilistic theories
Paulo J. Cavalcanti, John H. Selby, Jamie Sikora +1
Non-signalling quantum channels -- relevant in, e.g., the study of Bell and Einstein-Podolsky-Rosen scenarios -- may be simulated via affine combinations of local operations in bip…
A linear program for testing nonclassicality and an open-source implementation
John H. Selby, Elie Wolfe, David Schmid +2
A well motivated method for demonstrating that an experiment resists any classical explanation is to show that its statistics violate generalized noncontextuality. We here formulat…
On characterising assemblages in Einstein-Podolsky-Rosen scenarios
Vinicius P. Rossi, Matty J. Hoban, Ana Belén Sainz
Characterising non-classical quantum phenomena is crucial not only from a fundamental perspective, but also to better understand its capabilities for information processing and com…
Q-Turn: Changing Paradigms In Quantum Science
Ana Belén Sainz
Quantum information is a rapidly-growing interdisciplinary field at the intersection of information science, computer science, mathematics, philosophy, and quantum science, working…
Avenues to generalising Bell inequalities
Marcin Karczewski, Giovanni Scala, Antonio Mandarino +2
Characterizing the set of all Bell inequalities is a notably hard task. An insightful method of solving it in case of Bell correlation inequalities for scenarios with two dichotomi…
