Quantum sequential parameter testing
Simon Morelli, Ricard Ravell Rodríguez, John Calsamiglia +3
Sequential strategies in hypothesis testing use a variable number of measurement rounds, allowing a decision to be made as soon as the observed data provide a prescribed level of e…
Non-equilibrium quantum thermometry with bosonic samples
Marek Winczewski, Michał Horodecki, Ricard Ravell Rodríguez
We study low-temperature non-equilibrium quantum thermometry with a bosonic probe: a quantum harmonic oscillator strongly coupled to a bosonic bath at temperature through a Dru…
Quantum Resource Theories beyond Convexity
Roberto Salazar, Jakub Czartowski, Ricard Ravell Rodríguez +3
A class of quantum resource theories, based on non-convex star-shape sets, presented in this work captures the key quantum properties that cannot be studied by standard convex theo…
Existence of unbiased resilient estimators in discrete quantum systems
Javier Navarro, Ricard Ravell Rodríguez, Mikel Sanz
The Cramér-Rao bound serves as a crucial lower limit for the mean squared error of an estimator in frequentist parameter estimation. Paradoxically, it requires highly accurate prio…
An approximation scheme and non-Hermitian re-normalization for description of atom-field system evolution
Borhan Ahmadi, Ricard Ravell Rodríguez, Robert Alicki +1
Interactions between a source of light and atoms are ubiquitous in nature. The study of them is interesting on the fundamental level as well as for applications. They are in the co…
Optimal Quantum Control of Charging Quantum Batteries
R. R. Rodriguez, B. Ahmadi, G. Suarez +3
Quantum control allows us to address the problem of engineering quantum dynamics for special purposes. While recently the field of quantum batteries has attracted much attention, o…
On the edge of the set of no-signaling assemblages
Michał Banacki, Ricard Ravell Rodríguez, Paweł Horodecki
Following recent advancements, we consider a scenario of multipartite postquantum steering and general no-signaling assemblages. We introduce the notion of the edge of the set of n…
