This study shows a mixed quantum-classical guidance system that combines an eight-layer Quantum Approximate Optimization Algorithm (QAOA) with Proximal Policy Optimization (PPO) reinforcement learning for cities that do not have GNSS. The design changes the settings of the quantum circuit on the fly based on real-time data from the environment. This makes noise in cities less of a static mistake source and more of an optimization constraint. After testing on 47.3 kilometers of GNSS-denied paths in three cities using a three-tier DARPA QuANET-aligned protocol and NIST-traceable equipment, the results show that the average positional accuracy is 0.15 ± 0.03 meters, which is 70% better than high-grade GPS/INS systems. With adaptive correction, the framework keeps 98.2% of its coherence under ISO 16750-3 shaking and 95.3% of its operational reliability during 24-hour signal rejection. It also reduces drift by 82% compared to LiDAR-SLAM over a kilometer. It is statistically significant (F (3,1196) =87.3, p<0.001, ·²=0.38), and the effect sizes are big. The system passes SAE Level 4 power limits (45.2W), goes beyond DARPA QuANET 2025 goals, and gets Hybrid Readiness Level 7 approval. Each unit is expected to cost $210,000, and it creates the first policy-ready quantum navigation platform for smart city application.
