Comment on "Thermodynamic Principle for Quantum Metrology"
Shane Dooley, Michael J. Kewming, Mark T. Mitchison +1
In Phys. Rev. Lett. 128, 200501 (2022) the authors consider the thermodynamic cost of quantum metrology. One of the main results is $\mathcal{S} \geq \log(2) \| h_λ\|^{-2} F_Q [ψ_λ…
Out-of-time-order correlations and the fine structure of eigenstate thermalisation
Marlon Brenes, Silvia Pappalardi, Mark T. Mitchison +2
Out-of-time-order correlators (OTOCs) have become established as a tool to characterise quantum information dynamics and thermalisation in interacting quantum many-body systems. It…
Thermodynamics of precision in quantum nano-machines
Antoine Rignon-Bret, Giacomo Guarnieri, John Goold +1
Fluctuations strongly affect the dynamics and functionality of nanoscale thermal machines. Recent developments in stochastic thermodynamics have shown that fluctuations in many far…
Quantum fluctuations hinder finite-time information erasure near the Landauer limit
Harry J. D. Miller, Giacomo Guarnieri, Mark T. Mitchison +1
Information is physical but information is also processed in finite time. Where computing protocols are concerned, finite-time processing in the quantum regime can dynamically gene…
Quantum Coherence and Ergotropy
Gianluca Francica, Felix C. Binder, Giacomo Guarnieri +3
Constraints on work extraction are fundamental to our operational understanding of the thermodynamics of both classical and quantum systems. In the quantum setting, finite-time con…
In situ thermometry of a cold Fermi gas via dephasing impurities
Mark T. Mitchison, Thomàs Fogarty, Giacomo Guarnieri +3
The precise measurement of low temperatures is a challenging, important and fundamental task for quantum science. In particular, in-situ thermometry is highly desirable for cold at…
