Effective dynamics from minimising dissipation
Antonio F. Rotundo, Paolo Perinotti, Alessandro Bisio
It is known that the same physical system can be described by different effective theories depending on the scale at which it is observed. In this work, we formulate a prescription…
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…
Classification of qubit cellular automata on hypercubic lattices
Andrea Pizzamiglio, Alessandro Bisio, Paolo Perinotti
We classify quantum cellular automata whose cells are qubits, on hypercubic lattices , with the von Neumann neighborhood scheme, in terms of realizability as finite-de…
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…
Renormalisation of Quantum Cellular Automata
Lorenzo Siro Trezzini, Alessandro Bisio, Paolo Perinotti
We study a coarse-graining procedure for quantum cellular automata on hypercubic lattices that consists in grouping neighboring cells into tiles and selecting a subspace within eac…
A perturbative approach to the solution of the Thirring quantum cellular automaton
Alessandro Bisio, Paolo Perinotti, Andrea Pizzamiglio +1
The Thirring Quantum Cellular Automaton (QCA) describes the discrete time dynamics of local fermionic modes that evolve according to one step of the Dirac cellular automaton follow…
