The Bose-Marletto-Vedral experiment with nanodiamond interferometers: an insight on entanglement detection
Giuseppe Di Pietra, Fabrizio Piacentini, Ettore Bernardi +6
Recently, it has been proposed a new method [arXiv:2405.21029] to detect quantum gravity effects, based on generating gravitational entanglement between two nano-diamonds with Nitr…
Table-top nanodiamond interferometer enabling quantum gravity tests
Marta Vicentini, Ettore Bernardi, Matteo Bordin +6
Along the path of unifying quantum theory and general relativity, it has recently been argued that the observation of gravity-induced entanglement could demonstrate the quantum nat…
Quantum enhanced non-interferometric quantitative phase imaging
Giuseppe Ortolano, Alberto Paniate, Pauline Boucher +5
Quantum entanglement and squeezing have significantly improved phase estimation and imaging in interferometric settings beyond the classical limits. However, for a wide class of no…
Quantum-enhanced pattern recognition
Giuseppe Ortolano, Carmine Napoli, Cillian Harney +6
The challenge of pattern recognition is to invoke a strategy that can accurately extract features of a dataset and classify its samples. In realistic scenarios this dataset may be…
Towards superresolution surface metrology: Quantum estimation of angular and axial separations
Carmine Napoli, Samanta Piano, Richard Leach +2
We investigate the localization of two incoherent point sources with arbitrary angular and axial separations in the paraxial approximation. By using quantum metrology techniques, w…
