摘要: |
研究2个纠缠的二能级原子中的1个原子在与相干光场相互作用过程中,纠缠参量θ对另1个原子的偶极压缩的影响.结果表明,原子偶极算符的∏1分量不存在压缩,而∏2分量则存在压缩,∏2分量的压缩随表征相互作用时间的参量gt和相干光振幅|T|的增大而增大,而随纠缠参量θ呈负单峰变化,当gt=0.7、|T|=10及θ=π/4时,∏2分量在产生最大压缩的情况下呈现最大的量子纠缠. |

Abstract: |
The impact of entanglement parameter θ on atomic dipole squeezing of one of two entangled atoms in the process of entangled another atom interacting with coherent light is studied.The results show that the component ∏1 of the atomic dipole operator does not present squeezing, but the component ∏2 does, and that the squeezing of ∏2 increases with gt representing interacting time and cohere light amplitude |T| and presents a negative single-peak curve with entanglement parameter θ.When gt=0.7,|T|=10 and θ=π/4, the component ∏2 takes on the max squeezing accompany the max entanglement of the quantum state. |
