The system implements controllable fading memory via real-time electro-optic feedback, encodes data through programmable pump phase shaping, and retrieves it via mode-selective homodyne detection. Expressivity is enhanced through spatial multiplexing and by exploiting the entangled multimode structure. The platform successfully performs nonlinear temporal tasks including XOR, parity check at various delays, and chaotic signal forecasting (double-scroll, Lorenz). A high-fidelity Digital Twin accurately reproduces experimental results. The architecture achieves polynomial scaling of expressivity with measured modes and outperforms purely spatial multiplexing strategies, establishing a scalable room-temperature photonic platform for quantum-enhanced temporal information processing. ## Full article daily.dev links to this article rather than hosting it.
