NWQEC: Toward Efficient Fault-Tolerant Quantum Circuit Compilation

Oral-In-person

Abstract

 We present NWQEC, an open-source framework for transpiling and optimizing fault-tolerant quantum computing (FTQC). Beyond conventional circuit transformations, NWQEC integrates two recent advances to address key FTQC bottlenecks. The TACO (Transpiler–Architecture Codesign Optimization) framework applies architecture-informed circuit optimizations, achieving up to 91.7% reduction in Clifford gates and significantly enhancing gate-level parallelism. On the other hand, the TQC (Tableau-based Quantum Compiler) framework supports efficient FTQC optimization and compilation to Pauli-based computation. TQC achieves an average 2.57× speedup in FTQC runtime and over 1000× faster compilation compared to existing tools. Together, these frameworks make NWQEC a powerful and extensible platform for developing and evaluating resource-efficient FTQC pipelines.
