摘要
提出3种利用2个二粒子纠缠态作为量子通道,来传输一个未知的二粒子纠缠态的方案。首先考虑使用最大纠缠态作为量子通道,然后考虑使用非最大纠缠态。发现在使用非最大纠缠态作为量子通道时,通过引进一个辅助粒子,并构造一个幺正变换矩阵,即可以一定的几率完成二粒子纠缠态的隐形传输。
Three schemes of teleporting a two-particle entangled state via two pairs of entangled partieles are proposed. The maximally entangled states are first taken as quantum ehannels, then the ease of nonmaximally entangled channels is considered. We find that when the channels are nonmaximally entangled states by introdueing an aneillary qubit and eonstructing an unitary transformation properly, teleportation of two-particle entangled state can be implemented with eertain probability.
