Neuromorphic Physical Unclonable Function and SelfCoherent Receiver based on a Reconfigurable Photonic Circuit

We experimentally investigate a neuromorphic receiver which addresses impairments of a 32 Gbaud self-coherent QPSK transmission and simultaneously generates unclonable responses with an equal error below $10^{-9}$, suitable for security in the physical layer. © 2025 The Author(s)
