Quantum PUF for Security and Trust in Quantum Computing

Quantum computing is a promising paradigm to solve computationally intractable problems. Various companies such as, IBM, Rigetti and D-Wave offer quantum computers using cloud-based platform that possess several interesting features. These factors motivate new threat model. To mitigate this threat, we propose two flavors of QuPUF: one based on superposition, another decoherence. Experiments real IBM hardware show the proposed QuPUF can achieve inter-die Hamming Distance(HD) 55% intra-HD as low 4%, compared ideal cases 50% 0% respectively. The QuPUFs also be used standalone solution for any other application.
