Self-testing Quantum Supermaps
Victor Barizien, Cyril Branciard, Alastair A. Abbott +2
By certifying quantum operations from measurement statistics directly, without any assumption on the internal workings of the devices involved, self-testing enables a uniquely reli…
Indefinite Quantum Causality
Fabio Costa, Giulia Rubino, Cyril Branciard +2
In recent years, operational approaches to quantum foundations have been developed as a means of understanding the core principles and distinctive features of quantum theory. Such…
Correlations and quantum circuits with dynamical causal order
Raphaël Mothe, Raphaël Mothe, Alastair A. Abbott +1
Requiring that the causal structure between different parties is well-defined imposes constraints on the correlations they can establish, which define so-called causal correlations…
Routing Quantum Control of Causal Order
Maarten Grothus, Alastair A. Abbott, Augustin Vanrietvelde +1
In recent years, various frameworks have been proposed for the study of quantum processes with indefinite causal order. In particular, quantum circuits with quantum control of caus…
