The current focus on quantum error correction, with its reliance on massive qubit counts, overlooks a critical bottleneck in today’s NISQ hardware: signal bleeding during readout. Aggressive measurement hygiene offers more immediate improvements than brute-force error correction.
Measurement Hygiene for NISQ Hardware
Complex quantum circuits are often undermined by readout errors, not gate errors. The H.O.T. Framework emphasizes designing the entire workflow around readout limitations, focusing on error prevention during information extraction rather than post-processing.
Measurement Hygiene and NISQ Fidelity
Treating measurement outcomes as dynamic, filterable inputs can improve computational fidelity. Rejecting shots with anomalous qubit statistics, termed “orphaned measurements,” and focusing on the signal-to-noise ratio before inference.
NISQ Hardware: Measurement Hygiene for Superior Transpilation
The H.O.T. Framework, with its aggressive measurement hygiene, outperforms standard transpilation on benchmarks, extending circuit depth beyond theoretical limits. This suggests noisy readout is often the primary cause of circuit failure, not gate errors.
NISQ Hardware Measurement Hygiene: A Disciplined Approach
If your algorithms fail, prioritize measurement hygiene. Implement a robust strategy, define shot parameters based on your specific backend, and treat noise as a signal to be disciplined. Focus on clean measurements to get usable results from NISQ hardware today.
