Quantum sensing of a quantum field
Ricard Ravell Rodríguez, Martí Perarnau-Llobet, Pavel Sekatski
Estimating a classical parameter encoded in the Hamiltonian of a quantum probe is a fundamental and well-understood task in quantum metrology. A textbook example is the estimation…
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…
An information-theoretic proof of the Planckian bound for thermalization
Paolo Abiuso, Alberto Rolandi, John Calsamiglia +2
We demonstrate that quantum mechanics entails a fundamental lower bound on the thermalization time of any system. At finite temperature, we show that is bounded by half the…
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…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
