A purification postulate for quantum mechanics with indefinite causal order
Mateus Araújo, Adrien Feix, Miguel Navascués +1
To study which are the most general causal structures which are compatible with local quantum mechanics, Oreshkov et al. introduced the notion of a process: a resource shared betwe…

Causally nonseparable processes admitting a causal model
Adrien Feix, Mateus Araújo, Časlav Brukner
A recent framework of quantum theory with no global causal order predicts the existence of "causally nonseparable" processes. Some of these processes produce correlations incompati…
