Complete physical simulation of the entangling-probe attack on the Bennett-Brassard 1984 protocol
We have used deterministic single-photon two-qubit quantum logic to implement the most powerful individual-photon attack against the Bennett-Brassard 1984 (BB84) quantum key distribution protocol. Our measurement results, including physical source and gate errors, are in good agreement with theoretical predictions for the R\'enyi information obtained by Eve as a function …
