Guoqiang Cui, M. G. Raymer

摘要:

计算了腔量子电动力学强耦合条件下单光子源的积分脉冲量子效率。在Weisskopf-Wigner近似下得到了量子效率的解析表达式。高量子效率和时间局域化的光子发射率的最佳条件进行检查。我们给出了Law和Kimble [J.Mod.Opt.44,2067(1997)]的早期结果可以用作我们结果的第一近似的条件。

英文摘要:

We calculate the integrated-pulse quantum efficiency of single-photon sources in the cavity quantum electrodynamics (QED) strong-coupling regime. An analytical expression for the quantum efficiency is obtained in the Weisskopf-Wigner approximation. Optimal conditions for a high quantum efficiency and a temporally localized photon emission rate are examined. We show the condition under which the earlier result of Law and Kimble [J. Mod. Opt. 44, 2067 (1997)] can be used as the first approximation to our result.
