Extracting and charging energy into almost unknown quantum states
Andrea Canzio, Vasco Cavina, Roberto Menta +1
In this work, we investigate the amount of energy that can be extracted or charged through unitary operations when only minimal information about the state is known. Assuming knowl…
The entropic coherence is a necessary resource for non-energy preserving gates
Riccardo Castellano, Vasco Cavina, Marti Perarnau-Llobet +2
We consider the task of implementing non-energy preserving gates (NEPG) on a finite-dimensional system S via an energy-preserving interaction with an external battery B. We prove t…
Exact requirements for battery-assisted qubit gates
Riccardo Castellano, Vasco Cavina, Martí Perarnau-Llobet +2
We consider the implementation of a unitary gate on a qubit system S via a global energy-preserving operation acting on S and an auxiliary system B that can be seen as a battery. W…
Extracting energy via bosonic Gaussian operations
Frank Ernesto Quintela Rodriguez, Francesco Anna Mele, Salvatore Francesco Emanuele Oliviero +3
Quantum thermodynamics is often formulated as a theory with constrained access to operations and resources. In this manuscript, we find a closed formula for the Gaussian ergotropy,…
Exact non-Markovian master equations: a generalized derivation for Gaussian systems
Antonio D'Abbruzzo, Vittorio Giovannetti, Vasco Cavina
We derive an exact master equation that captures the dynamics of a quadratic quantum system linearly coupled to a Gaussian environment of the same statistics: the Gaussian Master E…
Unifying quantum stochastic methods using Wick's theorem on the Keldysh contour
Vasco Cavina, Antonio D'Abbruzzo, Vittorio Giovannetti
We present a method, based on the Keldysh formalism, for deriving stochastic master equations that describe the non-Markovian dynamics of a quantum system coupled to a Gaussian env…
