The composition rule for quantum systems is not the only possible one
Marco Erba, Paolo Perinotti
Quantum theory provides a significant example of two intermingling hallmarks of science: the ability to consistently combine physical systems and study them compositely, and the po…
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…
Measurement incompatibility is strictly stronger than disturbance
Marco Erba, Paolo Perinotti, Davide Rolino +1
The core of Heisenberg's heuristic argument for the uncertainty principle, involving the famous -ray microscope , hinges upon the existence of measu…
Classicality without local discriminability: decoupling entanglement and complementarity
Giacomo Mauro D'Ariano, Marco Erba, Paolo Perinotti
An operational probabilistic theory where all systems are classical, and all pure states of composite systems are entangled, is constructed. The theory is endowed with a rule for c…
Classical theories with entanglement
Giacomo Mauro D'Ariano, Marco Erba, Paolo Perinotti
We investigate operational probabilistic theories where the pure states of every system are the vertices of a simplex. A special case of such theories is that of classical theories…
Chirality from quantum walks without quantum coin
Giacomo Mauro D'Ariano, Marco Erba, Paolo Perinotti
Quantum walks (QWs) describe the evolution of quantum systems on graphs. An intrinsic degree of freedom---called the coin and represented by a finite-dimensional Hilbert space---is…
