Non-Orthogonal Bases for Quantum Metrology (2019)
Journal Article
Genoni, M. G., & Tufarelli, T. (2019). Non-Orthogonal Bases for Quantum Metrology. Journal of Physics A: Mathematical and Theoretical, 52(43), 1-18. https://doi.org/10.1088/1751-8121/ab3fe0

Many quantum statistical models are most conveniently formulated in terms of non-orthonormal bases. This is the case, for example, when mixtures and superpositions of coherent states are involved. In these instances, we show that the analytical evalu... Read More about Non-Orthogonal Bases for Quantum Metrology.

Towards superresolution surface metrology: quantum estimation of angular and axial separations (2019)
Journal Article
Napoli, C., Piano, S., Leach, R., Adesso, G., & Tufarelli, T. (2019). Towards superresolution surface metrology: quantum estimation of angular and axial separations. Physical Review Letters, 122(14), Article 140505. https://doi.org/10.1103/physrevlett.122.140505

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 show that a simultaneous estimation of the two separations is achiev...
