Thermofield-based chain mapping approach for open quantum systems
Ines de Vega, Mari-Carmen Bañuls
We consider a thermofield approach to analyze the evolution of an open quantum system coupled to an environment at finite temperature. In this approach, the finite temperature envi…
Quantum simulation of the Schwinger model: A study of feasibility
Stefan Kühn, J. Ignacio Cirac, Mari-Carmen Bañuls
We analyze some crucial questions regarding the practical feasibility of quantum simulation for lattice gauge models. Our analysis focuses on two models suitable for the quantum si…
Unifying Projected Entangled Pair States contractions
Michael Lubasch, J. Ignacio Cirac, Mari-Carmen Bañuls
The approximate contraction of a Projected Entangled Pair States (PEPS) tensor network is a fundamental ingredient of any PEPS algorithm, required for the optimization of the tenso…
Wigner function for a particle in an infinite lattice
Margarida Hinarejos, A. Pérez, Mari-Carmen Bañuls
We study the Wigner function for a quantum system with a discrete, infinite dimensional Hilbert space, such as a spinless particle moving on a one dimensional infinite lattice. We…
A study of Wigner functions for discrete-time quantum walks
M. Hinarejos, M. C. Banuls, A. Perez
We perform a systematic study of the discrete time Quantum Walk on one dimension using Wigner functions, which are generalized to include the chirality (or coin) degree of freedom.…
