Modelling quantum measurement dynamics: from decoherence to redundancy with site-hopping indistinguishable particles
Katja Schneeweiss, Tom Rivlin, Maximilian P. E. Lock +2
In recent years, new theoretical insights into decoherence and quantum measurements have emerged through the study of many-body dynamics in isolated quantum systems. It is now unde…
Quantum vs Classical Erasure: Equal Bounds but Unequal Costs
Jan Neuser, Jake Xuereb, Pharnam Bakhshinezhad +1
The paper compares how much energy is needed to erase a bit of information in classical versus quantum systems when resources are limited, showing that quantum erasure requires mor…
Autonomization of Quantum Systems and the Emergence of the Work Operator
Carlo Cepollaro, Danial Chughtai, Alberto Spalvieri +2
Estimation of work at the quantum scale remains a central challenge in quantum thermodynamics. Canonical approaches have a fundamental drawback: they assume classical control of th…
Quantum Time Crystal Clock and its Performance
Ludmila Viotti, Marcus Huber, Rosario Fazio +1
Understanding different aspects of time is at the core of many areas in theoretical physics. Minimal models of continuous stochastic and quantum clocks have been proposed to explor…
Exponential gain in clock precision using quantum correlated ticks
Florian Meier, Yuri Minoguchi, Gianmichele Blasi +2
Creating precise timing devices at ultra-short time scales is not just an important technological challenge, but confronts us with foundational questions about timekeeping's ultima…
Cooling a Qubit using n Others
Jake Xuereb, Benjamin Stratton, Alberto Rolandi +3
In the task of unitarily cooling a quantum system with access to a larger quantum system, known as the machine or reservoir, how does the structure of the machine impact an agent's…
