Quantum information and Artificial Neural Networks-based Signal Processing using Integrated Photonics

Integrated photonics is contributing to new emerging technologies for advanced signal processing, based on machine learning and quantum information science. In this work, we utilize compact, reconfigurable, on-chip devices to develop photonic artificial neural networks and quantum signal processors for telecommunication applications. Our work demonstrates the recovery and reconstruction of high-speed telecommunication signals with ultralow latency, as well as enhances the speed and security of quantum communication. Characterized by their highly efficient and intelligent processing, parallelization, and reduced power consumption, these technologies are set to pave the way for the next generation of telecom networks.
