Bare quantum simultaneity versus classical interactivity in communication complexity
Dmytro Gavinsky
TL;DR
This paper presents a relational bipartite communication problem demonstrating an efficient quantum simultaneous-messages protocol, contrasting with the lack of an efficient classical two-way protocol, highlighting quantum advantage in communication complexity.
Contribution
It introduces a specific problem showcasing quantum superiority over classical communication protocols in a bipartite setting.
Findings
Quantum protocol is efficient for the problem.
Classical protocol requires significantly more communication.
Quantum advantage is demonstrated in the problem context.
Abstract
A relational bipartite communication problem is presented that has an efficient quantum simultaneous-messages protocol, but no efficient classical two-way protocol.
