提出了玻色-爱因斯坦凝聚体叠加相干态的量子隐形传态方案。我们利用光子纠缠态作为量子通道，实现原子态的远距离隐形传态。介绍了两种健壮的方案：一种是单光子方案，其中纠缠的单光子态作为量子通道；另一种是多光子方案，其中探测激光器的纠缠相干态作为量子通道。
We propose protocols for quantum teleportation of superposed coherent states of atomic Bose—Einstein condensates. We use the photon entanglement states as the quantum channel, which makes it possible to realize the distant teleportation of atomic states. Two robust protocols are introduced: one is a single-photon scheme in which an entangled single-photon state serves as the quantum channel, and the other is a multi-photon scheme where an entangled coherent state of the probe lasers is used as the quantum channel.
