Non-linear Boson Sampling
Nicolò Spagnolo, Daniel J. Brod, Ernesto F. Galvão +1
Boson Sampling is a task that is conjectured to be computationally hard for a classical computer, but which can be efficiently solved by linear-optical interferometers with Fock st…
Non-asymptotic Heisenberg scaling: experimental metrology for a wide resources range
Valeria Cimini, Emanuele Polino, Federico Belliardo +5
Adopting quantum resources for parameter estimation discloses the possibility to realize quantum sensors operating at a sensitivity beyond the standard quantum limit. Such approach…
Quantum violation of local causality in urban network with hybrid photonic technologies
Gonzalo Carvacho, Emanuele Roccia, Mauro Valeri +13
Quantum networks play a crucial role for distributed quantum information processing, enabling the establishment of entanglement and quantum communication among distant nodes. Funda…
Reconfigurable continuously-coupled 3D photonic circuit for Boson Sampling experiments
Francesco Hoch, Simone Piacentini, Taira Giordani +10
Boson Sampling is a computational paradigm representing one of the most viable and pursued approaches to demonstrate the regime of quantum advantage. Recent results have demonstrat…
Witnesses of coherence and dimension from multiphoton indistinguishability tests
Taira Giordani, Chiara Esposito, Francesco Hoch +5
Quantum coherence marks a deviation from classical physics, and has been studied as a resource for metrology and quantum computation. Finding reliable and effective methods for ass…
Experimental statistical signature of many-body quantum interference
Taira Giordani, Fulvio Flamini, Matteo Pompili +8
Multi-particle interference is an essential ingredient for fundamental quantum mechanics phenomena and for quantum information processing to provide a computational advantage, as r…
