QFusion: A Demonstration of Boundary-Aware Fusion Planning and Execution for Large-Scale QUBO Optimization

Summary: QFusion is a DBMS-inspired, cost-based framework that plans boundary-aware fusion of decomposed QUBOs on an actual quantum annealer. Its interactive demonstration covers join ordering, multiple-query optimization, and index selection, exposing decomposition–fusion tradeoffs. (summarized by gpt-5.6-luna on Aug 28 2026)
