Extended local ergotropy
Riccardo Castellano, Donato Farina, Vittorio Giovannetti +1
A fundamental problem in quantum thermodynamics is to properly quantify the work extractable from out-of-equilibrium systems. While for closed systems, maximum quantum work extract…

Certification of quantum state functions under partial information
Leonardo Zambrano, Donato Farina, Egle Pagliaro +2
Convex functions of quantum states play a key role in quantum physics, with examples ranging from Bell inequalities to von Neumann entropy. However, in experimental scenarios, dire…

Deep Neural Network-assisted improvement of quantum compressed sensing tomography
Adriano Macarone-Palmieri, Leonardo Zambrano, Maciej Lewenstein +2
Quantum compressed sensing is the fundamental tool for low-rank density matrix tomographic reconstruction in the informationally incomplete case. We examine situations where the ac…
