Probabilistic metrology or how some measurement outcomes render ultra-precise estimates
J. Calsamiglia, B. Gendra, R. Munoz-Tapia +1
We show on theoretical grounds that, even in the presence of noise, probabilistic measurement strategies (which have a certain probability of failure or abstention) can provide, up…
Discrimination power of a quantum detector
Christoph Hirche, Masahito Hayashi, Emilio Bagan +1
We investigate the ability of a quantum measurement device to discriminate two states or, generically, two hypothesis. In full generality, the measurement can be performed a number…
Quantum change point
Gael Sentís, Emilio Bagan, John Calsamiglia +2
Sudden changes are ubiquitous in nature. Identifying them is of crucial importance for a number of applications in medicine, biology, geophysics, and social sciences. Here we inves…
