单原子在两个远红失谐光偶极阱中的转移
Transferring single-atoms between two red-detuned far-off-resonance optical dipole traps
-
摘要: 在光偶极阱中实现单个中性原子的囚禁及其操控在量子信息处理中具有重要的应用．为此在使用强聚焦远红失谐激光形成的光偶极阱囚禁单个中性铷原子后，通过一个空间可移动的光偶极阱从静止的光偶极阱上掠过，实现了将静止的光偶极阱中的单原子以94％的概率转移到可移动的光偶极阱中，并将该原子移动到焦平面上指定的位置．该实验对于实现光偶极阱阵列中任意两个原子的纠缠以及光偶极阱中原子外在自由度的操控等研究有着潜在的应用．Abstract: The preparation and manipulation of single neutral atoms in optical dipole traps have important applications in quantum simulation and information. For this purpose, a single neutral atom, trapped in a static optical dipole trap which is formed by a strongly focused red-detuned far-off-resonance laser, can be transferred to a movable optical dipole trap when the movable trap crosses the static trap and the transfer efficiency can reach about 94%, meanwhile this transferred atom could be located at given position in the focal plane. This experimental result has potential applications in realizing entanglement of two individual neutral atoms in an optical dipole trap array.
