Summary

An integrated hardware-aware compilation and data-driven quantum error-detection (QED) framework is presented to address the challenge of balancing error detection overhead against success probability under latency constraints for noisy intermediate-scale quantum (NISQ) processors. This framework jointly optimizes qubit mapping, SWAP insertion, and syndrome-schedule placement using a noise-weighted cost function and a learned multi-objective scheduler. It aims to improve algorithmic success rates in an early fault-tolerance regime where full quantum error correction is too resource-intensive. Simulation experiments, conducted on an HPC cluster with GPU-accelerated density-matrix simulation (NVIDIA cuQuantum SDK) across VQE, phase-estimation, and Grover benchmarks, demonstrate significant improvements. The framework raises algorithmic success probability by up to 68% (95% CI: 60% to 76%) over SABRE on an 8-qubit VQE instance with post-selection, for circuit sizes of 6-20 qubits and depths 10-160.

Key takeaway

For Research Scientists optimizing quantum algorithms on noisy intermediate-scale quantum (NISQ) hardware, you should prioritize integrated hardware-aware compilation and data-driven error detection. This approach, which jointly optimizes qubit mapping and error-syndrome scheduling, significantly improves algorithmic success rates by up to 68% compared to isolated methods. Integrating these processes can mitigate the prohibitive resource costs of full quantum error correction, making early fault-tolerant systems more viable.
