Quantum Communication Advantage for Leader Election and Agreement

Year: 2025

Type: conference-paper

Abstract: This work focuses on understanding the quantum message complexity of two central problems in distributed computing, namely, leader election and agreement in synchronous message-passing communication networks. We show that quantum communication gives an advantage for both problems by presenting quantum distributed algorithms that significantly outperform their respective classical counterparts under various network topologies.
