Causal inequalities witness non-stabilizerness
Leonardo Vaglini, Nasra Daher Ahmed, Ravi Kunjwal
Stabilizer operations describe a fragment of quantum theory that is known to be efficiently classically simulable, thanks to the Gottesman-Knill theorem. For this reason, nonstabil…
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…
Which entropy for general physical theories?
Paolo Perinotti, Alessandro Tosini, Leonardo Vaglini
We address the problem of quantifying the information content of a source for an arbitrary information theory, where the information content is defined in terms of the asymptotic a…
Shannon theory beyond quantum: information content of a source
Paolo Perinotti, Alessandro Tosini, Leonardo Vaglini
The information content of a source is defined in terms of the minimum number of bits needed to store the output of the source in a perfectly recoverable way. A similar definition…
Shannon theory for quantum systems and beyond: information compression for fermions
Paolo Perinotti, Alessandro Tosini, Leonardo Vaglini
We address the task of compression of fermionic quantum information. Due to the parity superselection rule, differently from the case of encoding of quantum information in qubit st…
