利用量子纠缠粒子对的远程关联可以实现隐形传态,这是在经典物理现象中找不到的最奇妙的特性,它在量子通信中可能会扮演一个非常特殊的角色。但是利用隐形传态通信能否实现超光速通信、能否突破经典通信的距离和速率极限?通过从量子特性和通信系统工程角度对这些问题进行详细分析可知量子通信存在一些局限性,其在对潜通信和深空通信领域的应用前景有限,对量子通信系统的特色和局限性进行客观分析具有重要意义。
Teleportation using quantum entangled particle pairs can achieve teleportation, the most marvelous feature that can not be found in classical physics. It may play a very special role in quantum communication. However, whether the use of teletype communication can achieve superluminal communication can break the limit of the distance and rate of classical communication. By analyzing these problems in detail from the perspectives of quantum characterization and communication system engineering, we know that quantum communication has some limitations. Sub-communication and deep space communications applications in the field of limited prospects for the characteristics and limitations of quantum communication systems for objective analysis is of great significance.
