Quantum complementarity
Davide Rolino, Paolo Perinotti, Alessandro Tosini
We propose an operational definition of complementarity, pinning down the concept originally introduced by Bohr. Two properties of a system are considered complementary if they can…
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…
Minimal operational theories: classical theories with quantum features
Davide Rolino, Marco Erba, Alessandro Tosini +1
We introduce a class of probabilistic theories, termed Minimal Strongly Causal Operational Probabilistic Theories, where system dynamics are constrained to the minimal set of opera…
Fermionic cellular automata in one dimension
Lorenzo S. Trezzini, Matteo Lugli, Paolo Meda +3
We consider quantum cellular automata for one-dimensional chains of Fermionic modes and study their implementability as finite depth quantum circuits. Fermionic automata have been…
The signaling dimension in generalized probabilistic theories
Michele Dall'Arno, Alessandro Tosini, Francesco Buscemi
The signaling dimension of a given physical system quantifies the minimum dimension of a classical system required to reproduce all input/output correlations of the given system. T…
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…
