One Compiler Cut a Quantum Workload 241-Fold

The framework converts hierarchical quantum algorithms into dependency-preserving schedules and time-resolved workloads, then co-designs surface-code layout, resource-state supply and execution. Across 20 circuits in seven families, similar logical counts produced very different physical costs. Under the authors’ direct-rotation calibration, choosing the non-Clifford implementation reduced space-time volume by as much as 241.5× for one QAOA amplitude-amplification workload. Tailored layouts lowered routed latency for every benchmark and lowered space-time volume for 13 of them.
