Application range of crosstalk-affected spatial demultiplexing for resolving separations between unbalanced sources
Tomasz Linowski, Konrad Schlichtholz, Giacomo Sorelli +4
Superresolution is one of the key issues at the crossroads of contemporary quantum optics and metrology. Recently, it was shown that for an idealized case of two balanced sources,…
Quantum limits for resolving Gaussian sources
Giacomo Sorelli, Manuel Gessner, Mattia Walschaers +1
We determine analytically the quantum Cramér-Rao bound for the estimation of the separation between two point sources in arbitrary Gaussian states. Our analytical expression is val…
Gaussian quantum metrology for mode-encoded parameters
Giacomo Sorelli, Manuel Gessner, Nicolas Treps +1
Quantum optical metrology aims to identify ultimate sensitivity bounds for the estimation of parameters encoded into quantum states of the electromagnetic field. In many practical…
Multiparameter quantum metrology and mode entanglement with spatially split nonclassical spin states
Matteo Fadel, Benjamin Yadin, Yuping Mao +2
We identify the multiparameter sensitivity of split nonclassical spin states, such as spin-squeezed and Dicke states spatially distributed into several addressable modes. Analytica…
Homodyne detection of non-Gaussian quantum steering
Carlos E. Lopetegui, Manuel Gessner, Matteo Fadel +2
Quantum correlations are at the core of current developments in quantum technologies. Certification protocols of entanglement and steering, suitable for continuous-variable non-Gau…
Estimation of a parameter encoded in the modal structure of a light beam: a quantum theory
Manuel Gessner, Nicolas Treps, Claude Fabre
Quantum light is described not only by a quantum state but also by the shape of the electromagnetic modes on which the state is defined. Optical precision measurements often estima…
