Integrated quantum photonics (IQP) has evolved from a laboratory curiosity into a practical foundation for metropolitan quantum networks. A major milestone in this field is the development of a heterogeneously integrated superconducting silicon-photonic chip, which combines the mature scalability of silicon-on-insulator (SOI) platforms with the extreme sensitivity of superconducting nanowire single-photon detectors (SNSPDs). 1. Core Architecture and Integration
