Discrete Feynman propagator for the Weyl quantum walk in 2+1 dimensions
G. M. D'Ariano, N. Mosco, P. Perinotti +1
Recently quantum walks have been considered as a possible fundamental description of the dynamics of relativistic quantum fields. Within this scenario we derive the analytical solu…
Quasi-quantization: classical statistical theories with an epistemic restriction
Robert W. Spekkens
A significant part of quantum theory can be obtained from a single innovation relative to classical theories, namely, that there is a fundamental restriction on the sorts of statis…
Quantum Cellular Automaton Theory of Light
Alessandro Bisio, Giacomo Mauro D'Ariano, Paolo Perinotti
We present a quantum theory of light based on quantum cellular automata (QCA). This approach allows us to have a thorough quantum theory of free electrodynamics encompassing an hyp…
Path-integral solution of the one-dimensional Dirac quantum cellular automaton
Giacomo Mauro D'Ariano, Nicola Mosco, Paolo Perinotti +1
Quantum cellular automata have been recently considered as a fundamental approach to quantum field theory, resorting to a precise automaton, linear in the field, for the Dirac equa…
The Feynman problem and Fermionic entanglement: Fermionic theory versus qubit theory
Giacomo Mauro D'Ariano, Franco Manessi, Paolo Perinotti +1
The present paper is both a review on the Feynman problem, and an original research presentation on the relations between Fermionic theories and qubits theories, both regarded in t…
