中文摘要：

一个新理论量钥匙分发计划基于纠纷交换被建议，在的地方 four-qubit 对称的 W 状态作为量 channei 工作。二个合法用户能秘密地由使用钟状态大小和古典通讯分享一系列关键位，这被显示出。

英文摘要：

A new theoretical quantum key distribution scheme based on entanglement swapping is proposed, where four-qubit symmetric W state functions as quantum channel. It is shown that two legitimate users can secretly share a series of key bits by using Bell-state measurements and classical communication.
