Almost quantum correlations and their refinements in a tripartite Bell scenario
James Vallins, Ana Belén Sainz, Yeong-Cherng Liang
We study the set of almost quantum correlations and their refinements in the simplest tripartite Bell scenario where each party is allowed to perform two dichotomic measurements. I…
On the tightness of correlation inequalities with no quantum violation
Ravishankar Ramanathan, Marco Túlio Quintino, Ana Belén Sainz +2
We study the faces of the set of quantum correlations, i.e., the Bell and noncontextuality inequalities without any quantum violation. First, we investigate the question whether ev…
Adjusting inequalities for detection-loophole-free steering experiments
Ana Belén Sainz, Yelena Guryanova, Will McCutcheon +1
We study the problem of certifying quantum steering in a detection-loophole-free manner in experimental situations that require post-selection. We present a method to find the modi…
Classical communication cost of quantum steering
Ana Belén Sainz, Leandro Aolita, Nicolas Brunner +2
Quantum steering is observed when performing appropriate local measurements on an entangled state. Here we discuss the possibility of simulating classically this effect, using clas…
