Ultimate quantum sensitivity in the estimation of the delay between two interfering photons through frequency-resolving sampling
Danilo Triggiani, Giorgos Psaroudis, Vincenzo Tamma
We demonstrate the ultimate sensitivity allowed by quantum physics in the estimation of the time delay between two photons by measuring their interference at a beam-splitter throug…
Non-adaptive Heisenberg-limited metrology with multi-channel homodyne measurements
Danilo Triggiani, Paolo Facchi, Vincenzo Tamma
We show a protocol achieving the ultimate Heisenberg-scaling sensitivity in the estimation of a parameter encoded in a generic linear network, without employing any auxiliary netwo…
Heisenberg-limited estimation robust to detector inefficiency in a multi-parameter Mach-Zehnder network with squeezed light
Dario Gatto, Paolo Facchi, Vincenzo Tamma
We propose a multi-parameter quantum metrological protocol based on a Mach-Zehnder interferometer with a squeezed vacuum input state and an anti-squeezing operation at one of its o…
Heisenberg scaling precision in the estimation of functions of parameters
Danilo Triggiani, Paolo Facchi, Vincenzo Tamma
We propose a metrological strategy reaching Heisenberg scaling precision in the estimation of functions of any number of arbitrary parameters encoded in a generic -channel l…
