Amplitude-amplified coherence detection and estimation
Rhea Alexander, Michalis Skotiniotis, Daniel Manzano
The detection and characterization of quantum coherence is of fundamental importance both in the foundations of quantum theory as well as for the rapidly developing field of quantu…

The geometry of passivity for quantum systems and a novel elementary derivation of the Gibbs state
Nikolaos Koukoulekidis, Rhea Alexander, Thomas Hebdige +1
Passivity is a fundamental concept that constitutes a necessary condition for any quantum system to attain thermodynamic equilibrium, and for a notion of temperature to emerge. Whi…
