Current fluctuations in a non-additive open quantum system: breakdown of the quantum-jump approach
Ilia Khomchenko, Saulo V. Moreira, Emanuel Schwarzhans +2
Open quantum system dynamics is efficiently described by the quantum master equation formalism. Therein, quantum master equations in Lindblad form constitute an important subclass…
Quantum detectors as autonomous machines: assessing the nonequilibrium thermodynamics of information acquisition
Emanuel Schwarzhans, Tony J. G. Apollaro, Ilia Khomchenko +3
We formulate a minimal model of a quantum particle detector as an autonomous quantum thermal machine. Our goal is to establish how entropy production, which is needed to maintain t…
Detection states of ions in a Paul trap via conventional and quantum machine learning algorithms
Ilia Khomchenko, Andrei Fionov, Artem Alekseev +4
Trapped ions are among the leading platforms for quantum technologies, particularly in the field of quantum computing. Detecting states of trapped ions is essential for ensuring hi…
Cyclic solid-state quantum battery: Thermodynamic characterization and quantum hardware simulation
Luca Razzoli, Giulia Gemme, Ilia Khomchenko +4
We introduce a cyclic quantum battery model, based on an interacting bipartite system, weakly coupled to a thermal bath. The working cycle of the battery consists of four strokes:…
