Paper Abstract

We show that single qubit quantum fingerprinting without shared randomness is feasible with linear optics and is demonstrably superior to its classical counterpart. Furthermore a shared source of entanglement, provided for example by a parametric down converter, permits 100% reliable quantum fingerprinting, which outperforms classical fingerprinting even with arbitrary amounts of shared randomness.
