    "abstract": "We demonstrate that the Byzantine Agreement Problem (BAP) in its weaker\nversion with detectable broadcast, can be solved using continuous variables\nGaussian states with Gaussian operations. The protocol uses genuine tripartite\nsymmetric entanglement, but differs from protocols proposed for qutrits or\nqubits. Contrary to the quantum key distribution (QKD) which is possible with\nall Gaussian states, for the BAP entanglement is needed, but not all tripartite\nentangled symmetric states can be used to solve the problem.",
