Finite steps optimise dissipation in stochastically controlled quantum systems
Theodore McKeever, Harry J. D. Miller, Ahsan Nazir
Motivated by the need for precise, energy-efficient, and experimentally realistic quantum control protocols, we investigate the thermodynamic cost of performing quantum step-equili…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Covariant currents and a thermodynamic uncertainty relation on curved manifolds
Harry J. D. Miller
A framework for defining stochastic currents associated with diffusion processes on curved Riemannian manifolds is presented. This is achieved by introducing an overdamped Stratono…
Generalised linear response theory for the full quantum work statistics
Giacomo Guarnieri, Jens Eisert, Harry J. D. Miller
We consider a quantum system driven out of equilibrium via a small Hamiltonian perturbation. Building on the paradigmatic framework of linear response theory (LRT), we derive an ex…
Quantum work statistics at strong reservoir coupling
Owen Diba, Harry J. D. Miller, Jake Iles-Smith +1
Determining the statistics of work done on a quantum system while strongly coupled to a reservoir is a formidable task, requiring the calculation of the full eigenspectrum of the c…
Energy measurements remain thermometrically optimal beyond weak coupling
Jonas Glatthard, Karen V. Hovhannisyan, Martí Perarnau-Llobet +2
We develop a general perturbative theory of finite-coupling quantum thermometry up to second order in probe-sample interaction. By assumption, the probe and sample are in thermal e…
Optimal control of dissipation and work fluctuations for rapidly driven systems
Alberto Rolandi, Martí Perarnau-Llobet, Harry J. D. Miller
To achieve efficient and reliable control of microscopic systems one should look for driving protocols that mitigate both the average dissipation and stochastic fluctuations in wor…
Finite-time bounds on the probabilistic violation of the second law of thermodynamics
Harry J. D. Miller, Martí Perarnau-Llobet
Jarzynski's equality sets a strong bound on the probability of violating the second law of thermodynamics by extracting work beyond the free energy difference. We derive finite-tim…
Thermodynamic length and work optimisation for Gaussian quantum states
Mohammad Mehboudi, Harry J. D. Miller
Constructing optimal thermodynamic processes in quantum systems relies on managing the balance between the average excess work and its stochastic fluctuations. Recently it has been…
Joint statistics of work and entropy production along quantum trajectories
Harry J. D. Miller, M. Hamed Mohammady, Martí Perarnau-Llobet +1
In thermodynamics, entropy production and work quantify irreversibility and the consumption of useful energy, respectively, when a system is driven out of equilibrium. For quantum…
Geometry of work fluctuations versus efficiency in microscopic thermal machines
Harry J. D. Miller, Mohammad Mehboudi
When engineering microscopic machines, increasing efficiency can often come at a price of reduced reliability due to the impact of stochastic fluctuations. Here we develop a genera…
Geometric optimisation of quantum thermodynamic processes
Paolo Abiuso, Harry J. D. Miller, Martí Perarnau-Llobet +1
Differential geometry offers a powerful framework for optimising and characterising finite-time thermodynamic processes, both classical and quantum. Here, we start by a pedagogical…
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…
Thermodynamic uncertainty relation in slowly driven quantum heat engines
Harry J. D. Miller, M. Hamed Mohammady, Martí Perarnau-Llobet +1
Thermodynamic Uncertainty Relations express a trade-off between precision, defined as the noise-to-signal ratio of a generic current, and the amount of associated entropy productio…
Quantum work statistics close to equilibrium
Matteo Scandi, Harry J. D. Miller, Janet Anders +1
We study the statistics of work, dissipation, and entropy production of a quantum quasi-isothermal process, where the system remains close to the thermal equilibrium along the tran…
Work fluctuations in slow processes: quantum signatures and optimal control
Harry J. D. Miller, Matteo Scandi, Janet Anders +1
An important result in classical stochastic thermodynamics is the work fluctuation--dissipation relation (FDR), which states that the dissipated work done along a slow process is p…
Energy-temperature uncertainty relation in quantum thermodynamics
Harry J. D. Miller, Janet Anders
It is known that temperature estimates of macroscopic systems in equilibrium are most precise when their energy fluctuations are large. However, for nanoscale systems deviations fr…
Leggett-Garg inequalities for quantum fluctuating work
Harry J. D. Miller, Janet Anders
The Leggett-Garg inequalities serve to test whether or not quantum correlations in time can be explained within a classical macrorealistic framework. We apply this test to thermody…
Measurement-dependent corrections to work distributions arising from quantum coherences
P. Solinas, H. J. D. Miller, J. Anders
For a quantum system undergoing a unitary process work is commonly defined based on the Two Projective Measurement (TPM) protocol which measures the energies of the system before a…
Entropy production and time-asymmetry in the presence of strong interactions
Harry J. D. Miller, Janet Anders
It is known that the equilibrium properties of open classical systems that are strongly coupled to a heat bath are described by a set of thermodynamic potentials related to the sys…
Time-reversal symmetric work distributions for closed quantum dynamics in the histories framework
Harry J. D. Miller, Janet Anders
A central topic in the emerging field of quantum thermodynamics is the definition of thermodynamic work in the quantum regime. One widely used solution is to define work for a clos…
