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…
Storage and retrieval of two unknown unitary channels
Michal Sedlák, Robert Stárek, Nikola Horová +3
We address the fundamental task of converting uses of an unknown unitary transformation into a quantum state (i.e., storage) and later retrieval of the transformation. Specific…
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…
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…
Photonic cellular automaton simulation of relativistic quantum fields: observation of Zitterbewegung
Alessia Suprano, Danilo Zia, Emanuele Polino +6
Quantum Cellular Automaton (QCA) is a model for universal quantum computation and a natural candidate for digital quantum simulation of relativistic quantum fields. Here we introdu…
