Quantum causal modelling
Fabio Costa, Sally Shrapnel
Causal modelling provides a powerful set of tools for identifying causal structure from observed correlations. It is well known that such techniques fail for quantum systems, unles…
Brief reply to "Can gravity account for the emergence of classicality?"
Igor Pikovski, Magdalena Zych, Fabio Costa +1
In a series of comments, Bonder et al. criticized our work on decoherence due to time dilation [Nature Physics 11, 668-672 (2015)]. First the authors erroneously claimed that our r…
Time Dilation in Quantum Systems and Decoherence: Questions and Answers
Igor Pikovski, Magdalena Zych, Fabio Costa +1
Recent work has shown that relativistic time dilation results in correlations between a particle's internal and external degrees of freedom, leading to decoherence of the latter. I…
The simplest causal inequalities and their violation
Cyril Branciard, Mateus Araújo, Adrien Feix +2
In a scenario where two parties share, act on and exchange some physical resource, the assumption that the parties' actions are ordered according to a definite causal structure yie…
Witnessing causal nonseparability
Mateus Araújo, Cyril Branciard, Fabio Costa +3
Our common understanding of the physical world deeply relies on the notion that events are ordered with respect to some time parameter, with past events serving as causes for futur…
