Abstract: Quantum mechanics provides several methods to generate and securelydistribute private lists of numbers suitably correlated to solve the ThreeByzantine Generals Problem. So far, these methods are based on three-qutritsinglet states, four-qubit entangled states, and three or two pairwise quantumkey distribution channels. Here we show that the problem can be solved using asingle qutrit. This scheme presents some advantages over previous schemes, andemphasizes the specific role of qutrits in basic quantum informationprocessing.
