Thermodynamic length in open quantum systems
Matteo Scandi, Martí Perarnau-Llobet
The dissipation generated during a quasistatic thermodynamic process can be characterised by introducing a metric on the space of Gibbs states, in such a way that minimally-dissipa…
Collective operations can extremely reduce work fluctuations
Martí Perarnau-Llobet, Raam Uzdin
We consider work extraction from copies of a quantum system. When the same work-extraction process is implemented on each copy, the relative size of fluctuations is expected to…
Dynamics of quantum measurements employing two Curie-Weiss apparatuses
Martí Perarnau-Llobet, Theo M. Nieuwenhuizen
Two types of quantum measurements, measuring the spins of an entangled pair and attempting to measure a spin at either of two positions, are analysed dynamically by apparatuses of…
Fluctuating work in coherent quantum systems: proposals and limitations
Elisa Bäumer, Matteo Lostaglio, Martí Perarnau-Llobet +1
One of the most important goals in quantum thermodynamics is to demonstrate advantages of thermodynamic protocols over their classical counterparts. For that, it is necessary to (i…
Quantum metrology with one-dimensional superradiant photonic states
V. Paulisch, M. Perarnau-Llobet, A. González-Tudela +1
Photonic states with large and fixed photon numbers, such as Fock states, enable quantum-enhanced metrology but remain an experimentally elusive resource. A potentially simple, det…
