【摘要】 量子纠缠具有纠缠转移和非局域性的特点,有利于提高信息传送的安全性。本文报道了利用量子纠缠转移,实现直接通讯的方案.由于信息传递不伴随粒子的传输,比ping-pong模型的通讯方案有较高的安全性。更多还原

【Abstract】 Quantum entanglement is characterized in swapping entanglement and non-local operation,suitable to improve security of information transmission.Here we propose a protocol of quantum secure direct communication by the characteristics of entanglement.It is more secure than the ping-pong quantum communication protocol,due to free from particles transfering in the information transmission.更多还原
