| 摘 要： | 本文提出一个基于原子和腔场共振相互作用传送未知原子直积态的腔QED方案,原子和腔场通过J-C哈密顿量发生共振相互作用.在这个方案里,我们只需要用两个原子接受被传送的原子态以及两个单模腔作为量子通道.该方案既不需要贝尔态测量,也不需要任何操作重构纠缠初态,并且传送成功的概率为100%.这个方案也可以推广到传送n个原子的直积态. |

| Abstract: | In this paper, we propose a simple scheme for transferring of a two-atom product state via cavity quantum electrodynamics. Our proposal is based on atom-cavity field resonant interaction, the atom interacts resonantly with the mode of the cavity according to the Jaynes-Cummings Hamiltonian. This proposal only requires two atoms for receiving the teleported state, and two cavities as the quantum channel. The scheme does not require performing any transformations to reconstruct the initial state and does not require Bell-state measurement. In addition, the transfer of the scheme has a successful probability of 100 percent in a simple manner. And the scheme can also be extended to transfer product state of n-atom. |
