Chipmunq 🐿
A Fault-Tolerant Compiler for Chiplet Quantum Architectures

Chipmunq is a compiler that enables mapping and routing FT circuits onto both monolithic and chiplet-based architectures in a scalable, QEC-patch-preserving, and architecture-aware manner, aligning with the evolving demands of near- and long-term quantum modular hardware architectures.

Key Features of Chipmunq

• The Chipmunq compiler: The first scalable, hardware-aware mapping and routing framework that bridges the gap between topological QEC codes and heterogeneous chiplet-based architectures.

• Noise-aware heuristics: A novel inter-chiplet routing strategy that incorporates link fidelity and congestion awareness, successfully suppressing logical error rates by up to two orders of magnitude in heterogeneous noise environments while maintaining QEC effectiveness below correction thresholds.

• Scalability benchmarking: An evaluation demonstrating that Chipmunq delivers 13.5x speedup on average in compilation time and an average 91.4% reduction in SWAP overhead compared to LightSABRE.
