Spurious quantum correlations

Shashaank Khanna, Matthew F. Pusey, Roger Colbeck

In his seminal paper, Bell [Physics Physique Fizika 1, 195 (1964)] considers the correlations that result from space-like separated measurements on a pair of entangled particles. H…

Higher rates for semi-device-independent randomness expansion by recycling input randomness

Rutvij Bhavsar, Hamid Tebyanian, Roger Colbeck

Although quantum random number generators rely on the inherent indeterminism of quantum mechanics, ensuring that the numbers produced are secure remains a significant challenge. We…

Closing the problem of which causal structures of up to six total nodes have a classical-quantum gap

Shashaank Khanna, Matthew Pusey, Roger Colbeck

The discovery of Bell that there exist quantum correlations that cannot be reproduced classically is one of the most important in the foundations of quantum mechanics, as well as h…

Correlation Self-Testing of Quantum Theory against Generalised Probabilistic Theories with Restricted Relabelling Symmetry

Kuntal Sengupta, Mirjam Weilenmann, Roger Colbeck

Correlation self-testing of quantum theory involves identifying a task or set of tasks whose optimal performance can be achieved only by theories that can realise the same set of c…

Genuine multipartite entanglement is not necessary for standard device-independent conference key agreement

Lewis Wooltorton, Peter Brown, Roger Colbeck

Conference key agreement aims to establish shared, private randomness among many separated parties in a network. Device-independent conference key agreement (DICKA) is a variant in…

Theories with no superluminal signaling have greater information-processing power than theories with no superluminal causation

V. Vilasini, Roger Colbeck

A central goal in the foundations of physics is to understand the structure of physical theories, such as quantum theory, from physical principles. This is often explored by consid…
