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…
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…
