Quantum Metrology Assisted with Abstention
B. Gendra, E. Ronco-Bonvehi, J. Calsamiglia +2
The main goal of quantum metrology is to obtain accurate values of physical parameters using quantum probes. In this context, we show that abstention, i.e., the possibility of gett…

Beating noise with abstention in state estimation
Bernat Gendra, Elio Ronco-Bonvehi, John Calsamiglia +2
We address the problem of estimating pure qubit states with non-ideal (noisy) measurements in the multiple-copy scenario, where the data consists of a number N of identically prepa…
