We report the wafer-scale fabrication, generation, and characterization of two-mode squeezed-vacuum states on a fully CMOS-compatible silicon nitride PIC platform. This work demonstrates excellent uniformity across a 4-inch wafer and establishes a reproducible route for scalable continuous-variable quantum information processing.
