Universality of Computation in Real Quantum Theory
Alessio Belenchia, Giacomo Mauro D'Ariano, Paolo Perinotti
Recently de La Torre et al. [1] reconstructed Quantum Theory from its local structure on the basis of local discriminability and the existence of a one-parameter group of bipartite…
Quantum Cloning by Cellular Automata
G. M. D'Ariano, C. Macchiavello, M. Rossi
We introduce a quantum cellular automaton that achieves approximate phase-covariant cloning of qubits. The automaton is optimized for 1-to-2N economical cloning. The use of the aut…
Quantum Field as a quantum cellular automaton: the Dirac free evolution in one dimension
Alessandro Bisio, Giacomo Mauro D'Ariano, Alessandro Tosini
We present a quantum cellular automaton model in one space-dimension which has the Dirac equation as emergent. This model, a discrete-time and causal unitary evolution of a lattice…
The Dirac Quantum Automaton: a preview
Giacomo Mauro D'Ariano
Quantum Information and the new informational paradigm are entering the domain of quantum field theory and gravity, suggesting the quantum automata framework. The quantum automaton…
Functional Quantum Computing: An Optical Approach
Timothy Rambo, Joseph Altepeter, Giacomo Mauro D'Ariano +1
A new model of quantum computing has recently been proposed which, in analogy with a classical lambda-calculus, exploits quantum processes which operate on other quantum processes.…
Quantum Theory, namely the pure and reversible theory of information
G. Chiribella, G. M. D'Ariano, P. Perinotti
After more than a century since its birth, Quantum Theory still eludes our understanding. If asked to describe it, we have to resort to abstract and ad hoc principles about complex…
