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…
Experimental Verification of an Indefinite Causal Order
Giulia Rubino, Lee A. Rozema, Adrien Feix +5
Investigating the role of causal order in quantum mechanics has recently revealed that the causal distribution of events may not be a-priori well-defined in quantum theory. While t…
Quantum superpositions of "common-cause" and "direct-cause" causal structures
Adrien Feix, Časlav Brukner
The constraints arising for a general set of causal relations, both classically and quantumly, are still poorly understood. As a step in exploring this question, we consider a cohe…
Exponential Communication Complexity Advantage from Quantum Superposition of the Direction of Communication
Philippe Allard Guérin, Adrien Feix, Mateus Araújo +1
In communication complexity, a number of distant parties have the task of calculating a distributed function of their inputs, while minimizing the amount of communication between t…
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…
