Coarse-grained dynamics in quantum many-body systems using the maximum entropy principle
Adán Castillo, Carlos Pineda, Erick Sebastían Navarrete +1
Starting from a coarse-grained map of a quantum many-body system, we construct the inverse map that assigns a microscopic state to a coarse-grained state based on the maximum entro…
Quantum simulation of Pauli channels and dynamical maps: algorithm and implementation
Tomas Basile, Carlos Pineda
Pauli channels are fundamental in the context of quantum computing as they model the simplest kind of noise in quantum devices. We propose a quantum algorithm for simulating Pauli…
Pauli component erasing quantum channels
Jose Alfredo de Leon, Alejandro Fonseca, Francois Leyvraz +2
Decoherence of quantum systems is described by quantum channels. However, a complete understanding of such channels, especially in the multi-particle setting, is still an ongoing d…
Fuzzy measurements and coarse graining in quantum many-body systems
Carlos Pineda, David Davalos, Carlos Viviescas +1
Using the quantum map formalism, we provide a framework to construct fuzzy and coarse grained quantum states of many-body systems that account for limitations in the resolution of…
Markovian and non-Markovian dynamics induced by a generic environment
M. Carrera, T. Gorin, C. Pineda
We study the open dynamics of a quantum two-level system coupled to an environment modeled by random matrices. Using the quantum channel formalism, we investigate different quantum…
Position representation of single-mode Gaussian channels beyond the Gaussian functional form
David Davalos, Camilo Moreno, Juan-Diego Urbina +1
We study one-mode Gaussian quantum channels in continuous-variable systems by performing a black-box characterization using complete positivity and trace preserving conditions, and…
