Efficient experimental validation of photonic boson sampling against the uniform distribution
N. Spagnolo, C. Vitelli, M. Bentivegna +10
A boson sampling device is a specialised quantum computer that solves a problem which is strongly believed to be computationally hard for classical computers. Recently a number of…
Joining and splitting the quantum states of photons
Elsa Passaro, Chiara Vitelli, Nicolo' Spagnolo +3
A photonic process named as "quantum state joining" has been recently experimentally demonstrated [C. Vitelli et al., Nature Photon. 7, 521 (2013)] that corresponds to the transfer…
Photonic polarization gears for ultra-sensitive angular measurements
V. D'Ambrosio, N. Spagnolo, L. Del Re +7
Quantum metrology bears a great promise in enhancing measurement precision, but is unlikely to become practical in the near future. Its concepts can nevertheless inspire classical…
General rules for bosonic bunching in multimode interferometers
N. Spagnolo, C. Vitelli, L. Sansoni +8
We perform a comprehensive set of experiments that characterize bosonic bunching of up to 3 photons in interferometers of up to 16 modes. Our experiments verify two rules that gove…
Quantum interferometry with three-dimensional geometry
N. Spagnolo, L. Aparo, C. Vitelli +5
Quantum interferometry uses quantum resources to improve phase estimation with respect to classical methods. Here we propose and theoretically investigate a new quantum interferome…
