On quantum illumination, quantum reading, and the capacity of quantum computation

Stefano Pirandola

In this brief note, I clarify the crucial differences between three different protocols of quantum channel discrimination, after some confusion has appeared in recent literature.

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…

Advances in Photonic Quantum Sensing

Stefano Pirandola, Bhaskar Roy Bardhan, Tobias Gehring +2

Quantum sensing has become a mature and broad field. It is generally related with the idea of using quantum resources to boost the performance of a number of practical tasks, inclu…

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.…
