摘要:

我们提出利用强偶极阻断机制中啁啾激光脉冲的绝热快速通过,从随机加载的光偶极阱或光晶格中确定性地只激发一个里德伯原子。啁啾激光激发被证明是不敏感的随机数\textit{N}的原子在陷阱。该方法克服了$\sqrt {N} $依赖于集体Rabi频率的问题,该问题是在具有未知\textit{N}的系综中确定性单原子激发的主要障碍,并可应用于偶极阱和光晶格的单原子加载.

英文摘要:

We propose to use adiabatic rapid passage with a chirped laser pulse in the strong dipole blockade regime to deterministically excite only one Rydberg atom from randomly loaded optical dipole traps or optical lattices. The chirped laser excitation is shown to be insensitive to the random number \textit{N} of the atoms in the traps. Our method overcomes the problem of the $\sqrt {N} $ dependence of the collective Rabi frequency, which was the main obstacle for deterministic single-atom excitation in the ensembles with unknown \textit{N}, and can be applied for single-atom loading of dipole traps and optical lattices.
