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…
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…
Quantum dynamics is not strictly bidivisible
David Davalos, Mario Ziman
We address the question of the existence of quantum channels that are divisible in two quantum channels but not in three or, more generally, channels divisible in but not in $n…
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…
Divisibility classes of qubit maps and singular Gaussian channels
David Davalos
We present two projects concerning the main part of my PhD work. In the first one we study quantum channels, which are the most general operations mapping quantum states into quant…
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…
