Objective
Emerging threats from quantum computing and increasingly sophisticated counterfeiting demand a new class of authentication technologies rooted in the laws of physics. QuantumPUF will develop scalable Physical Unclonable Functions (PUFs) with security guarantees based on quantum and statistical physical principles. We will design and implement three classes of photonic PUFs: (i) classical PUFs, (ii) quantum-readout PUFs, and (iii) quantum PUFs (Q-PUFs), the latter modeled as quantum channels (completely positive trace-preserving maps). These systems will be realized using two complementary luminescent platforms—layered organic–inorganic hybrid nanoparticles and lanthanide-based coordination complexes—engineered for spectral purity, high quantum yield, and environmental stability.QuantumPUF will exploit emission lifetime, spectral signatures, and spatial disorder to encode challenge-response pairs in multiple physical dimensions (spectral, spatial, temporal). Control of photon flux compatible with quantum-limited detection will enable secure optical readout using CMOS sensors. PUFs will be fabricated via scalable techniques such as spin-coating, inkjet printing, and electrospinning, incorporating stochastic disorder through material microstructure and processing variability.Security will be ensured through theoretical and experimental analysis, including min-entropy evaluation, side-channel vulnerability assessment, and the adaptation of device-independent quantum cryptographic certification protocols. For QPUFs, we will extend self-testing tools to quantum channels under minimal assumptions. For the most practical solutions, readout will be achieved using portable optical setups integrated into smartphones. QuantumPUF aims to define a unified quantum-secure authentication framework, combining novel photonic materials with foundational cryptographic tools, to establish a new technological and scientific frontier in physical security.
