Quantum distinguishability measures: projectors vs. states maximization
Adrian A. Budini, Ruynet L. de Matos Filho, Marcelo F. Santos
The distinguishability between two quantum states can be defined in terms of their trace distance. The operational meaning of this definition involves a maximization over measureme…
Usefulness of Quantum Entanglement for Enhancing Precision in Frequency Estimation
Marco A. Rodríguez-García, Ruynet L. de Matos Filho, Pablo Barberis-Blostein
We investigate strategies for reaching the ultimate limit on the precision of frequency estimation when the number of probes used in each run of the experiment is fixed. That limit…
Quantum advantage of time-reversed ancilla-based metrology of absorption parameters
Jiaxuan Wang, Ruynet. L. de Matos Filho, Girish S. Agarwal +1
Quantum estimation of parameters defining open-system dynamics may be enhanced by using ancillas that are entangled with the probe but are not submitted to the dynamics. Here we co…
Robust interferometric sensing using two-photon interference
G. H. Aguilar, R. S. Piera, P. L. Saldanha +2
Precise measurement of the angular deviation of an object is a common task in science and technology. Many methods use light for this purpose. Some of these exploit interference ef…
