Bell Inequalities From No-Signalling Distributions
Thomas Cope, Roger Colbeck
A Bell inequality is a constraint on a set of correlations whose violation can be used to certify non-locality. They are instrumental for device-independent tasks such as key distr…

Analysing causal structures in generalised probabilistic theories
Mirjam Weilenmann, Roger Colbeck
Causal structures give us a way to understand the origin of observed correlations. These were developed for classical scenarios, but quantum mechanical experiments necessitate thei…

A framework for quantum-secure device-independent randomness expansion
Peter J. Brown, Sammy Ragy, Roger Colbeck
A device-independent randomness expansion protocol aims to take an initial random seed and generate a longer one without relying on details of how the devices operate for security.…
