Entanglement and teleportation in quantum key distribution for secure wireless systems

Entanglement-assisted quantum key distribution (QKD) has attracted significant attention for its ability to provide highly secure wireless systems. This work explores the employment of quantum teleportation and the quantum Fourier transform (QFT) in entanglement-assisted QKD to enhance security. By integrating the concepts of entanglement, teleportation, and QFT, the key distribution strategy is significantly improved, leading to more secure communication. The system has been thoroughly tested for quantum bit error rate, secure key rate, and reconciliation efficiency. The results show that this technique outperforms the standard BB84 protocol. Based on their simulations, this protocol appears to be a promising technique for providing quantum-level security to next-generation wireless communication systems.
