Quantum State Measurement System With Dynamic Oracle Adaptation for Enhanced Parameter Estimation in NISQ Devices

This paper presents a novel quantum measurement system that integrates Simon’s period detection with Grover’s amplitude amplification through Dynamic Oracle Adaptation (DOA) for enhanced parameter measurement in Noisy Intermediate-Scale Quantum (NISQ) devices. Traditional hybrid quantum measurement approaches suffer from mid-circuit measurement-induced decoherence and static oracle construction, limiting measurement success probability to 15% under realistic noise conditions on IBM quantum hardware. Our proposed DOA measurement system eliminates mid-circuit state collapse by dynamically synthesizing measurement oracles based on period detection results, achieving measurement success probability improvements from 15% to 60% on IBM Brisbane quantum processor. The system achieves query complexity ofO(√2n−1/k) while maintaining quantum coherence throughout the measurement process. Experimental validation on IBM quantum hardware demonstrates superior performance for 4-qubit parameter estimation tasks under realistic device constraints. The measurement architecture exhibits broad applicability for cryptographic key detection, genomic sequence measurement, and graph parameter estimation, establishing a robust framework for practical quantum instrumentation systems.
