Disentangling signalling and causal influence
Kathleen Barsse, Paolo Perinotti, Alessandro Tosini +1
The causal effects activated by a quantum interaction are studied, modelling the last one as a bipartite unitary channel. The two parties, say Alice and Bob, can use the channel to…

Causal influence versus signalling for interacting quantum channels
Kathleen Barsse, Paolo Perinotti, Alessandro Tosini +1
A causal relation between quantum agents, say Alice and Bob, is necessarily mediated by an interaction. Modelling the last one as a reversible quantum channel, an intervention of A…
