    "abstract": "The Fuchs-Peres-Brandt (FPB) probe realizes the most powerful individual\nattack on Bennett-Brassard 1984 quantum key distribution (BB84 QKD) by means of\na single controlled-NOT (CNOT) gate. This paper describes a complete physical\nsimulation of the FPB-probe attack on polarization-based BB84 QKD using a\ndeterministic CNOT constructed from single-photon two-qubit quantum logic.\nAdding polarization-preserving quantum nondemolition measurements of photon\nnumber to this configuration converts the physical simulation into a true\ndeterministic realization of the FPB attack.",
