Quantum tomography as a tool for the characterization of optical devices
G. Mauro D'Ariano, Matteo G. A. Paris, Martina De Laurentis +2
We describe a novel tool for the quantum characterization of optical devices. The experimental setup involves a stable reference state that undergoes an unknown quantum transformat…
Improving quantum interferometry by using entanglement (to take a decision you'd better use entanglement)
G. M. D'Ariano, Matteo G. A Paris, Paolo Perinotti
We address the use of entanglement to improve the precision of generalized quantum interferometry, i.e. of binary measurements aimed to determine whether or not a perturbation has…
Nearly ideal binary communication in squeezed channels
Matteo G. A. Paris
We analyze the effect of squeezing the channel in binary communication based on Gaussian states. We show that for coding on pure states, squeezing increases the detection probabili…
Optimal quantum estimation of the coupling between two bosonic modes
G. Mauro D'Ariano, Matteo G. A. Paris, Paolo Perinotti
We address the problem of the optimal quantum estimation of the coupling parameter of a bilinear interaction, such as the transmittivity of a beam splitter or the internal phase-sh…
A robust verification of the quantum nature of light
Matteo G. A. Paris
We present a conditional experiment involving a parametric amplifier and an avalanche photodetector to generate highly nonclassical states of the radiation field. The nonclassicali…
