Abstract Robust Integrable Quantum Optical Sources, Constructed by Topological Boundary States, Are Crucial for the on‐chip Information Processing. However, Limited Bulk‐edge Correspondence, Implementation of Channels Necessitates a Substantial Number Bulk Sites, Which Notably Diminishes Ratio Ring Resonators to Generate Sources. How Achieve Topologically‐protected Sources With Extremely Enhanced Utilization Efficiency Remains Challenge. Here, First Realization Hyperbolic is reported, Possess Dominated Than That in Domain. Specifically, Require Fewer Resources (i.e., number ring resonators) Same Level Brightness Compared Euclidean Furthermore, Correlated‐ and Entangled‐photon Pairs Measured. The Work Possesses Potential Applications Circuits Suggests Novel Way on Exploration Physics Non‐Euclidean Space.
