摘要
提出了一种简单高效的量子不经意传输协议。该协议可以利用现有技术轻松实现，并且只要接收方不具备将粒子任意长时间存储的技术，就能抵御具有无限算力的作弊者。所提出的协议相较于先前协议有显著改进。与Crépeau和Kilian的协议（仅当粒子自旋沿x或y轴测量时才安全）不同，本协议无论沿何种轴测量粒子自旋都完全安全；与Bennett等人的协议（需要数万个粒子）不同，本协议仅需两个粒子。

备注
11 pages, LaTeX file, no figures. The structure of the OT protocol is the same as before: Alice sends two particles to Bob, with the spin of the particles along the horizontal or vertical axis. The proof of the security of the protocol has been made more clear. Some new references have been added
