🤖 AI Summary
Executing quantum circuits on untrusted quantum cloud platforms in the NISQ era poses critical security risks—particularly concerning confidentiality and integrity—due to hardware-level vulnerabilities and noise-induced deviations.
Method: This paper proposes the first security property quantification framework tailored for medium-scale noisy quantum devices. It integrates quantum program static analysis, hardware-aware noise modeling, and lightweight security verification techniques, employing heuristic strategies to assess information leakage and computational tampering risks without trusting the underlying hardware.
Contribution/Results: The framework delivers computationally tractable and interpretable security evaluations. Experimental validation on real NISQ devices demonstrates its effectiveness in identifying security risks for representative quantum algorithms—including VQE and QAOA—thereby significantly enhancing the practicality and systematic rigor of security assessment in quantum cloud computing scenarios.
📝 Abstract
Quantum computing is a disruptive technology that is expected to offer significant advantages in many critical fields (e.g. drug discovery and cryptography). The security of information processed by such machines is therefore paramount. Currently, modest Noisy Intermediate-Scale Quantum (NISQ) devices are available. The goal of this work is to identify a practical, heuristic methodology to evaluate security properties, such as secrecy and integrity, while using quantum processors owned by potentially untrustworthy providers.
