Sintesi del contesto e degli obiettivi generali del progetto

Bio-inspired computational models and quantum computing redefine computation beyond traditional architectures. PROMETHEUS aims to unite quantum and neuromorphic photonics, breaking barriers for enhanced performance. The heart of this endeavor is a Photonic Integrated Circuit (PIC) on silicon-on-insulator (SOI) featuring a Field Programmable Photonic Gate Array (FPPGA) synaptic layer. Fortified by energy-efficient non-volatile barium titanate (BTO) phase shifters and co-integrated III-V lasers, it forms an ultra-fast spiking neural layer. Advanced packaging techniques create a robust, adaptable device with unmatched low power consumption and rapid processing. PROMETHEUS' versatile platform explores spiking networks, reservoir computing, and quantum neural networks, catering to industry-driven applications like high-speed image processing for biomedical and industrial sectors. The PIC's functions extend to quantum random number generation (QRNG) and photonic physical unclonable function (PUF) for cybersecurity, enhancing both neuromorphic processing and hardware-based authentication.
