[[File:ByzantineAgreementFig.PNG|frame|Schematic representation of an execution of a Byzantine Agreement protocol with <math>n = 5</math> nodes and <math>t = 1</math> Byzantine failure. The red bits indicate the input value of each node, whereas the green bit represents the output. The solution shown satisfies the ''agreement'' and ''validity'' properties. The quantum Byzantine agreement protocol in the strongest possible failure model requires <math>{O}(1)</math> expected number of rounds, whereas a classical lower bound of <math>{\Omega}(\sqrt{n / \log(n)})</math> is known.]]

Here we will sketch the outline of the Fast Quantum Byzantine Agreement protocol by Ben-Or [[Quantum Byzantine Agreement#References|(3)]] that solves Byzantine Agreement using quantum resources. A very nice summary of this protocol is also presented in [[Quantum Byzantine Agreement#References|(1)]].
