Quantum Teleportation

定义 Definition

量子传态(量子隐形传态):一种量子信息处理方法,利用量子纠缠与经典通信,把一个量子态的“信息”从一个位置转移到另一个位置,而不需要把承载该量子态的粒子本身移动过去。常见于量子通信与量子计算研究。(注意:这不是科幻中的“传送人/物体”。)

词源 Etymology

quantum 源自拉丁语 quantum(“多少、量”),在物理学中指“量子”。teleportation 由 *tele-*(“远距”)+ portare(拉丁语“携带”)构成,意为“远距离传送”。“量子传态”这一术语在现代量子信息科学语境中固定下来,典型的理论方案在1993年由Bennett等人提出并广为传播。

例句 Examples

Quantum teleportation can transfer a qubit’s state to another lab.
量子传态可以把一个量子比特的状态转移到另一间实验室。

In quantum networks, teleportation combined with entanglement swapping enables long-distance distribution of quantum states without directly sending fragile particles through the entire channel.
在量子网络中,把量子传态与纠缠交换结合起来,可以在不让脆弱粒子直接穿越整段信道的情况下,实现量子态的远距离分发。
