High-Dimensional Methods for Quantum Homodyne Tomography
Nicola Mosco, Lorenzo Maccone
We provide optimized recursion relations for homodyne tomography. We improve previous methods by mitigating the divergences intrinsic in the calculation of the pattern functions us…
Scattering and perturbation theory for discrete-time dynamics
Alessandro Bisio, Nicola Mosco, Paolo Perinotti
We present a systematic treatment of scattering processes for quantum systems whose time evolution is discrete. We define and show some general properties of the scattering operato…
Solutions of a two-particle interacting quantum walk
Alessandro Bisio, Giacomo Mauro D'Ariano, Nicola Mosco +2
We study the solutions of the interacting Fermionic cellular automaton introduced in Ref. [Phys Rev A 97, 032132 (2018)]. The automaton is the analogue of the Thirring model with b…
Path-sum solution of the Weyl Quantum Walk in 3+1 dimensions
Giacomo Mauro D'Ariano, Nicola Mosco, Paolo Perinotti +1
We consider the Weyl quantum walk in 3+1 dimensions, that is a discrete-time walk describing a particle with two internal degrees of freedom moving on a Cayley graph of the group $…
A Python program for the implementation of the Γ-method for Monte Carlo simulations
Barbara De Palma, Marco Erba, Luca Mantovani +1
We present a modular analysis program written in Python devoted to the estimation of autocorrelation times for Monte Carlo simulations by means of the -method algorithm. We give…
Discrete time Dirac quantum walk in 3+1 dimensions
Giacomo Mauro D'Ariano, Nicola Mosco, Paolo Perinotti +1
In this paper we consider quantum walks whose evolution converges to the Dirac equation one in the limit of small wave-vectors. We show exact Fast Fourier implementation of the Dir…
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…
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…
