Quantum circuits for discrete-time quantum walks with position-dependent coin operator
Ugo Nzongani, Julien Zylberman, Carlo-Elia Doncecchi +3
The aim of this paper is to build quantum circuits that implement discrete-time quantum walks having an arbitrary position-dependent coin operator. The position of the walker is en…
From curved spacetime to spacetime-dependent local unitaries over the honeycomb and triangular Quantum Walks
Pablo Arrighi, Giuseppe Di Molfetta, Iván Márquez-Martín +1
A discrete-time Quantum Walk (QW) is an operator driving the evolution of a single particle on the lattice, through local unitaries. Some QW admit, as their continuum limit, a well…
The Dirac equation as a quantum walk over the honeycomb and triangular lattices
Pablo Arrighi, Giuseppe Di Molfetta, Iván Márquez-Martín +1
A discrete-time Quantum Walk (QW) is essentially an operator driving the evolution of a single particle on the lattice, through local unitaries. Some QWs admit a continuum limit, l…
Fermion confinement via Quantum Walks in 2D+1 and 3D+1 spacetime
I. Marquez-Martin, G. Di Molfetta, A. Perez
We analyze the properties of a two and three dimensional quantum walk that are inspired by the idea of a brane-world model put forward by Rubakov and Shaposhnikov [1]. In that mode…
Mimicking spatial localization in dynamical random environment
Ivan Marquez-Martin, Giuseppe Di Molfetta, Armando Perez
We study the role played by noise on the QW introduced in [1], a 1D model that is inspired by a two particle interacting QW. The noise is introduced by a random change in the value…
Asymptotic properties of the Dirac quantum cellular automaton
A. Pérez
We show that the Dirac quantum cellular automaton [Ann. Phys. 354 (2015) 244] shares many properties in common with the discrete-time quantum walk. These similarities can be exploi…
Information of a qubit interacting with a multilevel environment
A. Perez
We consider the interaction of a small quantum system (a qubit) with a structured environment consisting on many levels. The qubit will experience a decoherence process, which impl…
Screening effects in Relativistic Models of Dense Matter at Finite Temperature
Joaquin Diaz-Alonso, Armando Perez, Horacio D. Sivak
We investigate screening effects of the medium on the potential interaction between two static 'charges' for different models of dense plasmas in the one-boson exchange approximati…
