Minimizing back-action through entangled measurements
Kang-Da Wu, Elisa Bäumer, Jun-Feng Tang +5
When an observable is measured on an evolving coherent quantum system twice, the first measurement generally alters the statistics of the second one, which is known as measurement…
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…
Optimal Quantum Thermometry with Coarse-grained Measurements
Karen V. Hovhannisyan, Mathias R. Jørgensen, Gabriel T. Landi +3
Precise thermometry for quantum systems is important to the development of new technology, and understanding the ultimate limits to precision presents a fundamental challenge. It i…
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…
Weakly invasive metrology: quantum advantage and physical implementations
M. Perarnau-Llobet, D. Malz, J. I. Cirac
We consider the estimation of a Hamiltonian parameter of a set of highly photosensitive samples, which are damaged after a few photons are absorbed, for a total time…
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…
