Exploring the limits of no backward in time signalling
Yelena Guryanova, Ralph Silva, Anthony J. Short +3
We present an operational and model-independent framework to investigate the concept of no-backwards-in-time signaling. We define no-backwards-in-time signaling conditions, closely…
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…
Connecting processes with indefinite causal order and multi-time quantum states
Ralph Silva, Yelena Guryanova, Anthony J. Short +3
Recently, the possible existence of quantum processes with indefinite causal order has been extensively discussed, in particular using the formalism of process matrices. Here we gi…
