Quantum State Geometry String Framework (QSG‑String) : Toward a 4D Quantum State Geometry String Theory

Quantum State Geometry (QSG‑String) reformulates string theory as emergent bundles of geodesics in Hilbert space. This approach derives the Nambu‑Goto action, string tension, critical dimensions, and Regge trajectories directly from Fubini‑Study geometry, eliminating the need for Calabi‑Yau compactification. By fixing the vacuum uniquely through anomaly cancellation, QSG‑String provides a deterministic alternative to the landscape problem and bridges quantum geometry with string dynamics.
