Quantum sequential parameter testing
Simon Morelli, Ricard Ravell RodrÃguez, 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, MichaÅ Horodecki, Ricard Ravell RodrÃguez
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 RodrÃguez +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 RodrÃguez, 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 pri…
