Trustworthy Quantum Machine Learning: A Roadmap for Reliability, Robustness, and Security in the NISQ Era

  • 提出三支柱可信体系:不确定性量化、抗攻击鲁棒性、隐私保护。
  • 在NISQ设备上验证,发现不确定性与风险相关,量子扰动更难攻击。
  • 适合关注量子AI安全与可靠部署的研究者与工程师。

量子机器学习(QML)是解决经典人工智能难以应对的计算难题的有前景范式。然而,量子力学的固有概率性、当前NISQ硬件的设备噪声以及混合量子-经典执行流程引入了新风险,阻碍了QML在真实世界、安全关键场景中的可靠部署。本研究提出了可信量子机器学习(TQML)的综合路线图,整合三个可靠性基础支柱:(i) 不确定性量化以实现校准和风险感知决策,(ii) 针对经典与量子原生威胁模型的对抗鲁棒性,(iii) 在分布式和委托量子学习场景中的隐私保护。我们基于量子信息理论形式化了量子特定的信任度量,包括基于方差的预测不确定性分解、基于迹距离的鲁棒性边界,以及针对混合学习通道的差分隐私。为验证在现有NISQ设备上的可行性,我们在参数化量子分类器上验证了统一的信任评估流程,揭示了不确定性与预测风险之间的相关性,发现经典与量子态扰动攻击漏洞存在不对称性,以及由采样噪声和量子信道噪声驱动的隐私-效用权衡。该路线图旨在将可信度定义为量子AI设计的首要目标。

原文摘要 · Abstract (English)

Quantum machine learning (QML) is a promising paradigm for tackling computational problems that challenge classical AI. Yet, the inherent probabilistic behavior of quantum mechanics, device noise in NISQ hardware, and hybrid quantum-classical execution pipelines introduce new risks that prevent reliable deployment of QML in real-world, safety-critical settings. This research offers a broad roadmap for Trustworthy Quantum Machine Learning (TQML), integrating three foundational pillars of reliability: (i) uncertainty quantification for calibrated and risk-aware decision making, (ii) adversarial robustness against classical and quantum-native threat models, and (iii) privacy preservation in distributed and delegated quantum learning scenarios. We formalize quantum-specific trust metrics grounded in quantum information theory, including a variance-based decomposition of predictive uncertainty, trace-distance-bounded robustness, and differential privacy for hybrid learning channels. To demonstrate feasibility on current NISQ devices, we validate a unified trust assessment pipeline on parameterized quantum classifiers, uncovering correlations between uncertainty and prediction risk, an asymmetry in attack vulnerability between classical and quantum state perturbations, and privacy-utility trade-offs driven by shot noise and quantum channel noise. This roadmap seeks to define trustworthiness as a first-class design objective for quantum AI.
