    "abstract": "We analyze and demonstrate the feasibility and superiority of linear optical\nsingle-qubit fingerprinting over its classical counterpart. For one-qubit\nfingerprinting of two-bit messages, we prepare `tetrahedral\u0027 qubit states\nexperimentally and show that they meet the requirements for quantum\nfingerprinting to exceed the classical capability. We prove that shared\nentanglement permits 100% reliable quantum fingerprinting, which will\noutperform classical fingerprinting even with arbitrary amounts of shared\nrandomness.",
