Abstract

We present a fast quantum Byzantine Agreement protocol that can reach agreement in O(1) expected communication rounds against a strong full information, dynamic adversary, tolerating up to the optimal t < n/3 faulty players in the synchronous setting, and up to t < n/4 faulty players for asynchronous systems. This should be contrasted with the known classical synchronous lower bound of ω(√ n/log n) [3] when t = ω(n).
