基于四粒子W态的量子密钥分配协议
THE QUANTUM KEY DISTRIBUTION PROTOCOL BASED ON FOUR-PARTICLE W STATE
摘要
Abstract
The entanglement property of quantum can be effectively and safely applied to the quantum key distribution protocol.This paper presented a key distribution protocol based on four-particle W states.The quantum W state was characterized by strong robustness after quantum bit was lost,and the detection channel was distinguished from the key generation particle by using different measurement bases.Finally,the key was measured by both Bell measurement and the operator to generate a consistent message for both parties.Except for the particles used for channel detection,the rest of the particles were involved in the generation of the final key,making the particles more efficient.Finally,the security of the proposed four-key W-state key distribution protocol was analyzed.关键词
