I will discuss advances in photonic computing architectures leveraging hardware noise as a computational resource. Using nanoscale phase-change materials allows in-memory processing of probabilistic data. Photonic crossbar arrays utilizing chaotic light as entropy sources enable parallel, energy-efficient, high-speed probabilistic machine learning beyond traditional hardware limits. [more]
