Almost Quantum Correlations are Inconsistent with Specker's Principle
Tomáš Gonda, Ravi Kunjwal, David Schmid +2
Ernst Specker considered a particular feature of quantum theory to be especially fundamental, namely that pairwise joint measurability of sharp measurements implies their global jo…
A formalism for steering with local quantum measurements
A. B. Sainz, L. Aolita, M. Piani +2
We develop a unified approach to classical, quantum and post-quantum steering. The framework is based on uncharacterised (black-box) parties performing quantum measurements on thei…
A channel-based framework for steering, non-locality and beyond
Matty J. Hoban, Ana Belén Sainz
Non-locality and steering are both non-classical phenomena witnessed in Nature as a result of quantum entanglement. It is now well-established that one can study non-locality indep…
Almost quantum correlations violate the no-restriction hypothesis
Ana Belén Sainz, Yelena Guryanova, Antonio Acín +1
To identify which principles characterize quantum correlations, it is essential to understand in which sense this set of correlations differs from that of almost quantum correlatio…
Multipartite Composition of Contextuality Scenarios
Ana Belén Sainz, Elie Wolfe
Contextuality is a particular quantum phenomenon that has no analogue in classical probability theory. Given two independent systems, a natural question is how to represent such a…
