Quantum-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

Quantum metrology holds the promise of an early practical application of quantum
technologies, in which measurements of physical quantities can be made with much greater …

Quantum metrology is one of the most promising applications of quantum technologies. The
aim of this research field is the estimation of unknown parameters exploiting quantum …

We investigate the ultimate precision achievable in Gaussian quantum metrology. We derive
general analytical expressions for the quantum Fisher information matrix and for the …

Multiparameter estimation is a general problem that aims at measuring unknown physical
quantities, obtaining high precision in the process. In this context, the adoption of quantum …

We provide the optimal measurement strategy for a class of noisy channels that reduce to
the identity channel for a specific value of a parameter (spreading channels). We provide an …

We investigate the localization of two incoherent point sources with arbitrary angular and
axial separations in the paraxial approximation. By using quantum metrology techniques, we …

Since the initial discovery of quantum teleportation, it is devoted to transferring unknown
quantum states from one party to another distant partner. However, in the scenarios of …

We discuss the Heisenberg limit in the multiparameter metrology within two different
paradigms: one where the measurement is repeated many times (so the Cramér-Rao bound …

We study super-resolution imaging theoretically using a distant n-mode interferometer in the
microwave regime for passive remote sensing, used, eg, for satellites like the “Soil Moisture …
