Quantum simulation of bosonic-fermionic non-interacting particles in disordered systems via quantum walk
Francesco De Nicola, Linda Sansoni, Andrea Crespi +6
We report on the theoretical analysis of bosonic and fermionic non-interacting systems in a discrete two-particle quantum walk affected by different kinds of disorder. We considere…
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…
Integrated optical waveplates for arbitrary operations on polarization-encoded single-qubits
Giacomo Corrielli, Andrea Crespi, Roberto Osellame +6
Integrated photonic technologies applied to quantum optics have recently enabled a wealth of breakthrough experiments in several quantum information areas. Path encoding was initia…
Observation of surface states with algebraic localization
G. Corrielli, G. Della Valle, A. Crespi +2
We introduce and experimentally demonstrate a class of surface bound states with algebraic decay in a one-dimensional tight-binding lattice. Such states have an energy embedded in…
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…
Anderson localization of entangled photons in an integrated quantum walk
Andrea Crespi, Roberto Osellame, Roberta Ramponi +5
Waves fail to propagate in random media. First predicted for quantum particles in the presence of a disordered potential, Anderson localization has been observed also in classical…
Fractional Bloch oscillations in photonic lattices
Giacomo Corrielli, Andrea Crespi, Giuseppe Della Valle +2
Bloch oscillations, the oscillatory motion of a quantum particle in a periodic potential, are one of the most fascinating effects of coherent quantum transport. Originally studied…
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…
