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…

Characterisation of multi-level quantum coherence without ideal measurements
Benjamin Dive, Nikolaos Koukoulekidis, Stefanos Mousafeiris +1
Coherent superpositions are one of the hallmarks of quantum mechanics and are vital for any quantum mechanical device to outperform the classically achievable. Generically, superpo…
