Typicality of Contextuality
Vinicius P. Rossi, Beata Zjawin, Roberto D. Baldijão +5
Identifying when observed statistics cannot be explained by any reasonable classical model is a central problem in quantum foundations. A principled and universally applicable appr…
The resource theory of causal influence and knowledge of causal influence
Marina Maciel Ansanelli, Beata Zjawin, David Schmid +5
Understanding and quantifying causal relationships between variables is essential for reasoning about the physical world. In this work, we develop a resource-theoretic framework to…
Robust self-testing of quantum steering assemblages via operator inequalities
Beata Zjawin
Robust self-testing provides a framework for certifying quantum resources under experimental imperfections. Improving robustness bounds for quantum resources such as quantum states…
Activation of post-quantumness in bipartite generalised EPR scenarios
Beata Zjawin, Matty J. Hoban, Paul Skrzypczyk +1
In a standard bipartite Einstein-Podolsky-Rosen (EPR) scenario, Alice and Bob share a system prepared in an entangled state and Alice performs local measurements. One possible gene…
