二能级系统源的单光子控制理论

Theory of Single Photon Control from a Two Level System Source

Yong He, Eli Barkai

摘要:

从单个发射器产生单个光子或一对光子对于量子信息应用是重要的。利用生成函数理论,研究了方波激光脉冲的少光子需求理论和快速绝热跟踪方法。利用精确理论和数值解设计了二能级发射体的控制场,在有限的激光场强度和有限的相互作用时间的约束下,得到了最佳的单光子源和双光子源。与Brunel等人的实验比较,表明实验接近最佳条件。

英文摘要:

Generation of a single photon or a pair of photons from a single emitter is important for quantum information applications. Using the generating function formalism we investigate the theory of a few photons on demand for the square laser pulse and the rapid adiabatic following method. Exact theory and numerical solutions are used to design control fields for a two level emitter, which yield an optimal single or two photon source, under the constrains of finite laser field strength and finite interaction time. Comparison to experiments of Brunel et al, shows that the experiments were made close to optimal conditions.
