Why Quantum Hardware Needs Its Own Threat Model

AI-summarised brief · reviewed before publication

The article argues that the emerging field of quantum computing lacks a dedicated threat model, despite its rapid commercialization as a cloud service. While post‑quantum cryptography protects classical systems from future quantum attacks, no comparable effort secures the quantum hardware itself. Modern quantum machines consist of classical components—compilers, schedulers, calibration databases, and error‑correction decoders—connected to the internet for job submission via platforms such as IBM, AWS Braket, Azure Quantum, Google, IonQ and Quantinuum. This exposure creates attack surfaces ranging from supply‑chain compromises of software stacks to malicious manipulation of calibration data, decoder inputs, and multi‑tenant crosstalk. Existing research documents concrete exploits, but the findings remain fragmented, lacking a unified framework for vendors and security teams to assess and mitigate risks.

💡 Why It Matters

  • · Without a coherent security framework, quantum cloud providers risk undetected manipulation that could corrupt results, undermine trust, and give malicious users a covert channel to sabotage or steal computations.
