摘要:

提出了一种在高精细度光腔中从N个三能级原子中确定性地产生N光子Fock态的方案。该方法应用一个外部激光脉冲产生一个$N$ -光子输出态,同时使原子-腔系统保持在光学暗态的子空间内。我们提出了分析估计的误差,由于从这些暗态的振幅泄漏一般N,并比较它与N \leq 5的数值模拟的明确结果。所示的方法提供了一个强大的N-光子态源在各种实验条件下,是适合于实验实施使用云的冷原子磁捕获在一个腔。所得到的N光子态在非经典态的基础研究和量子信息处理中具有潜在的应用。

英文摘要:

We present a scheme for the deterministic generation of N-photon Fock states from N three-level atoms in a high-finesse optical cavity. The method applies an external laser pulsethat generates an $N$-photon output state while adiabatically keeping the atom-cavity system within a subspace of optically dark states. We present analytical estimates of the error due to amplitude leakage from these dark states for general N, and compare it with explicit results of numerical simulations for N \leq 5. The method is shown to provide a robust source of N-photon states under a variety of experimental conditions and is suitable for experimental implementation using a cloud of cold atoms magnetically trapped in a cavity. The resulting N-photon states have potential applications in fundamental studies of non-classical states and in quantum information processing.
