Bell and EPR experiments with signalling data
Lucas Maquedano, Sophie Egelhaaf, Amro Abou-Hachem +4
The no-signalling principle is a fundamental assumption in Bell-inequality and quantum-steering experiments. Nonetheless, experimental imperfections can lead to apparent violations…

Two-time quantities as elements of physical reality
Lucas Maquedano, Alexandre D. Ribeiro, Ana C. S. Costa +1
In recent years, time correlators have received renewed attention, especially under the guise of identifiers of nonclassical correlations. However, the physical interpretation of t…

Analysis of Quantum Steering Measures
L. Maquedano, A. C. S. Costa
The effect of quantum steering describes a possible action at a distance via local measurements. In the last few years, several criteria have been proposed to detect this type of c…
