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…
Thermodynamics of Hamiltonian anyons with applications to quantum heat engines
Joe Dunlop, Ãlvaro Tejero, Michalis Skotiniotis +1
The behavior of a collection of identical particles is intimately linked to the symmetries of their wavefunction under particle exchange. Topological anyons, arising as quasipartic…
Super-resolution of partially coherent bosonic sources
JoaquÃn López-Suárez, Michalis Skotiniotis
We consider imaging of two partially coherent sources and derive the ultimate quantum limits for estimating the separation, location, relative intensity, and coherence factor. We s…
Amplitude-amplified coherence detection and estimation
Rhea Alexander, Michalis Skotiniotis, Daniel Manzano
The detection and characterization of quantum coherence is of fundamental importance both in the foundations of quantum theory as well as for the rapidly developing field of quantu…
Superresolving collective quantum measurements
J. O. de Almeida, M. Lewenstein, M. Skotiniotis
We demonstrate a method for super-resolving signals encoded as finite mixtures of bosonic modes using collective measurements that exploit permutation symmetry. Specifically, we us…
Sequential analysis in a continuous spin-noise quantum sensor
Elisabet Roda-Salichs, Giulio Gasbarri, Antoni Alou +5
Many control and detection applications require real-time analysis of signals from sensors, in order to quickly and accurately act upon events revealed by the sensors. Such signal…
