| 摘 要： | 本文研究了绝热条件下，三能级Λ系统实现布居数转移和相干的两种方法，并比较了激光脉冲序列对布居数转移效率和相干的影响。运用自洽方程和密度矩阵方程，得出了相干控制量子态和布居数的数值模拟图。我们可以看到运用反直觉的脉冲序列比通常的脉冲序列在实现布居数转移和相干上更容易更优越。

| Abstract: | Two approaches of achieving population transfer and coherence are investigated for the three-level Λ system in the adiabatic limit. The effects of the laser pulse sequence on the population transfer efficiency and coherence are studied. Coherent control of quantum state and population is studied by numerical simulation based on self-consistent set of density matrix equations. It can be seen that the counterintuitive pulse sequence is more efficient in population transfer and coherence than the intuitive one. |
