The Influence of Quantum Entanglement on the Atomic Dipole Squeezing
YI Shi-guang · Guangxi kexue · 2009
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 |α| and presents a negative single-peak curve with entanglement parameter θ.When gt=0.7,|α|=10 and θ=π/4,the component ∏2 takes on the max squeezing accompany the max entanglement of the quantum state.
