General Expressions for the Quantum Fisher Information Matrix with Applications to Discrete Quantum Imaging (2021)
Journal Article
Fiderer, L. J., Tufarelli, T., Adesso, G., & Piano, S. (2021). General Expressions for the Quantum Fisher Information Matrix with Applications to Discrete Quantum Imaging. PRX Quantum, 2(2), Article 020308. https://doi.org/10.1103/prxquantum.2.020308

The quantum Fisher information matrix is a central object in multiparameter quantum estimation theory. It is usually challenging to obtain analytical expressions for it because most calculation methods rely on the diagonalization of the density matri...

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...

Theory of genuine tripartite nonlocality of Gaussian states (2014)
Journal Article
Adesso, G., & Piano, S. (2014). Theory of genuine tripartite nonlocality of Gaussian states. Physical Review Letters, 112(1), https://doi.org/10.1103/PhysRevLett.112.010401

We investigate the genuine multipartite nonlocality of three-mode Gaussian states of continuous variable systems. For pure states, we present a simplified procedure to obtain the maximum violation of the Svetlichny inequality based on displaced parit...

Genuine tripartite entanglement and nonlocality in Bose-Einstein condensates by collective atomic recoil (2013)
Journal Article
Piano, S., & Adesso, G. (2013). Genuine tripartite entanglement and nonlocality in Bose-Einstein condensates by collective atomic recoil. Entropy, 15(5), https://doi.org/10.3390/e15051875

We study a system represented by a Bose-Einstein condensate interacting with a cavity field in presence of a strong off-resonant pumping laser. This system can be described by a three-mode Gaussian state, where two are the atomic modes corresponding...
