We are pleased to share that our team member Franco Cirillo presented his work at IEEE QCNC 2026 in Kobe, titled Scalable Quantum Device Authentication Using Hardware-Efficient Quantum Physical Unclonable Functions.
In this work, we introduce a practical and scalable approach to quantum device authentication based on hardware-efficient quantum PUFs that exploit the intrinsic noise of NISQ systems, without requiring quantum memory. We specifically investigated the scalability of our QPUF circuits, obtaining promising results as the system size increases.
The approach was validated on real IBM quantum processors with up to 32 qubits, showing clear distinguishability between devices and strong potential for robust authentication in future quantum infrastructures.
This contribution represents a meaningful step toward secure and scalable quantum technologies.
