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…
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
Irreversibility has a fundamental thermodynamic cost, erasing information inevitably generates heat. This connection is quantified by the Landauer bound, which gives the minimum di…
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…
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…
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…
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…
Entropic costs of extracting classical ticks from a quantum clock
Vivek Wadhia, Florian Meier, Federico Fedele +12
We experimentally realize a quantum clock by using a charge sensor to count charges tunneling through a double quantum dot (DQD). Individual tunneling events are used as the clock'…
Reconstructing thermal states using dimensionally limited probes : A Model for Limited Control & Memory in Quantum Thermodynamics
Jake Xuereb, A. de Oliveira Junior, Fabien Clivaz +2
Whilst the complexity of acquiring knowledge of a quantum state has been extensively studied in the fields of quantum tomography and quantum learning, a physical understanding of i…
Optimal limits of continuously monitored thermometers and their Hamiltonian structure
Mohammad Mehboudi, Florian Meier, Marcus Huber +1
We investigate the fundamental and practical precision limits of thermometry in bosonic and fermionic environments by coupling an -level probe to them and continuously monitorin…
Precision is not limited by the second law of thermodynamics
Florian Meier, Yuri Minoguchi, Simon Sundelin +4
Physical devices operating out of equilibrium are inherently affected by thermal fluctuations, limiting their operational precision. This issue is pronounced at microscopic and esp…
Emergence of a second law of thermodynamics in isolated quantum systems
Florian Meier, Tom Rivlin, Tiago Debarba +3
The second law of thermodynamics states that the entropy of an isolated system can only increase over time. This appears to conflict with the reversible evolution of isolated quant…
Autonomous Quantum Processing Unit: An Autonomous Thermal Computing Machine & its Physical Limitations
Florian Meier, Marcus Huber, Paul Erker +1
Computation is an input-output process, where a program encoding a problem to be solved is inserted into a machine that outputs a solution. Quantum computation conventionally relie…
Quantum Coding with Finite Thermodynamic Resources
Jake Xuereb, Tiago Debarba, Marcus Huber +1
Quantum direct coding or Schumacher compression generalised the ideas of Shannon theory, gave an operational meaning to the von Neumann entropy and established the term qubit. But…
Experimental high-dimensional entanglement certification and quantum steering with time-energy measurements
Kai-Chi Chang, Murat Can Sarihan, Paul Erker +8
High-dimensional entanglement provides unique ways of transcending the limitations of current approaches in quantum information processing, quantum communications based on qubits.…
