With the emergence of sixth-generation (6G) wireless networks, ensuring information-theoretic security at extremely high data rates has become a critical challenge. Conventional cryptographic techniques are increasingly vulnerable to quantum computing attacks, motivating the integration of Quantum Key Distribution (QKD) with advanced wireless technologies. This paper proposes a hybrid QKD–Massive MIMO framework operating in the terahertz (THz) band (10–30 THz) to evaluate secure key generation performance under realistic distance, frequency, and antenna scaling conditions. A security-aware Secret Key Rate (SKR) model is developed by incorporating Quantum Bit Error Rate (QBER) constraints and distance-dependent attenuation. Extensive simulations analyze SKR variation with transmission distance (1–10 m), carrier frequency, and antenna array size (32–1024). Results demonstrate that massive MIMO significantly enhances SKR and extends the secure communication range, while higher THz frequencies introduce stronger attenuation. The proposed framework validates the feasibility of scalable quantum-secure THz communications for future 6G networks.
