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…
Positivity and complete positivity of differentiable quantum processes
Gustavo Montes Cabrera, David Davalos, Thomas Gorin
We study quantum processes, as one parameter families of differentiable completely positive and trace preserving (CPTP) maps. Using different representations of the generator, and…
Divisibility of qubit channels and dynamical maps
David Davalos, Mario Ziman, Carlos Pineda
The concept of divisibility of dynamical maps is used to introduce an analogous concept for quantum channels by analyzing the \textit{simulability} of channels by means of dynamica…
Quantum non-Markovianity and localization
David Davalos, Carlos Pineda
We study the behavior of non-Markovianity with respect to the localization of the initial environmental state. The "amount" of non-Markovianity is measured using divisibility and d…
