Approaching the Limit of Quantum Clock Precision
Chad Nelmes, Emanuel Schwarzhans, Tony Apollaro +2
Precise and autonomous clocks are of fundamental interest and central importance to both foundational studies and practical applications. Here, we construct a blueprint for a quant…
Average Equilibration Time for Gaussian Unitary Ensemble Hamiltonians
Emanuel Schwarzhans, Alessandro Candeloro, Felix C. Binder +2
Understanding equilibration times in closed quantum systems is essential for characterising their approach to equilibrium. Chaotic many-body systems are paradigmatic in this contex…
Quantum measurements and equilibration: the emergence of objective outcomes via entropy maximisation
Emanuel Schwarzhans, Felix C. Binder, Marcus Huber +1
The measurement postulate of quantum theory stands in conflict with the laws of thermodynamics and has evoked debate regarding what actually constitutes a measurement. With the hel…
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…
