Quantum Key Distribution Based on Quantum Entanglement
Jincheng Zhang
Abstract
This paper proposes a novel distributed key generation scheme based on quantum entanglement, aiming to achieve fully secure key distribution without prior key exchange. The core concept leverages quantum entanglement between two or more nodes to generate and transmit keys, combined with a quantum key distribution protocol for verification and error correction. Unlike existing quantum key distribution schemes reliant on quantum communication channels, this approach offers a theoretically more secure and potentially efficient method for key sharing. The system utilizes Bell states, polarization measurements, and post-processing techniques to establish a shared key. We outline the key components of the system, including entanglement generation, measurement protocols, error correction, and key distillation. The theoretical analysis demonstrates the security of the scheme against eavesdropping attacks, assuming the validity of quantum mechanics. This work contributes to the ongoing research in quantum cryptography and provides a foundational design for a future generation of secure communication networks.
