    "abstract": "We study the robustness of various protocols for quantum key distribution. We\nfirst consider the case of qutrits and study quantum protocols that employ two\nand three mutually unbiased bases. We then derive the optimal eavesdropping\nstrategy for two mutually unbiased bases in dimension four and generalize the\nresult to a quantum key distribution protocol that uses two mutually unbiased\nbases in arbitrary finite dimension.",
