Jamming Extensions of Quantum Correlations Lead to Hidden Superluminal Signaling
Ravishankar Ramanathan, Xie Sicheng, Michał Eckstein +1
Relativistic causality in certain spacetime configurations permits jamming - superluminal causal influences that nevertheless do not enable superluminal signaling. We fully charact…
The operational no-signalling constraints and their implications
Michał Eckstein, Tomasz Miller, Ryszard Horodecki +2
The study of quantum correlations within relativistic spacetimes, and the consequences of relativistic causality on information processing using such correlations, has gained much…
Linear game non-contextuality and Bell inequalities - a graph-theoretic approach
Piotr Gnaciński, Monika Rosicka, Ravishankar Ramanathan +4
We study the classical and quantum values of one- and two-party linear games, an important class of unique games that generalizes the well-known XOR games to the case of non-binary…
Local Realism of Macroscopic Correlations
Ravishankar Ramanathan, Tomasz Paterek, Alastair Kay +2
We show that for macroscopic measurements which cannot reveal full information about microscopic states of the system, the monogamy of Bell inequality violations present in quantum…
