Gaussian phase sensitivity of boson-sampling-inspired strategies
Antonio A. Valido, Juan José García-Ripoll
In this work we study the phase sensitivity of generic linear interferometric schemes using Gaussian resources and measurements. Our formalism is based on the Fisher information. T…

Quantum dissipation of planar harmonic systems: Maxwell-Chern-Simons theory
Antonio A. Valido
The conventional Brownian motion in harmonic systems has provided a deep understanding of a great diversity of dissipative phenomena. We address a rather fundamental microscopic de…

Quantum correlations and energy currents across finite harmonic chains
Antonio A. Valido, Antonia Ruiz, Daniel Alonso
We present a study that addresses both the stationary properties of the energy current and quantum correlations in a three-mode chain subjected to Ohmic and super-Ohmic dissipa- ti…
