论文摘要
我们使用具有99.91（2）％检测保真度和0.9（2）％检测驱动的亮态原子损失的简单探针梁对光学镊子中的地面高精灵歧管歧视。我们的检测不忠于0.09（2）％的数量级，比以前发布的光学镊子中碱金属原子的低损失读数结果要好。我们的低原子损失和高保真状态检测消除了由于探针激光器存在时，由于激发型型旋转螺旋杆之间的种群转移引起的额外的沉重机制。在这项工作中，不需要复杂的光学系统和严格的真空压力。
We demonstrate discrimination of ground-state hyperfine manifolds of a cesium atom in an optical tweezer using a simple probe beam with 99.91(2)% detection fidelity and 0.9(2)% detection-driven loss of bright state atoms. Our detection infidelity of 0.09(2)% is an order of magnitude better than previously published low-loss readout results for alkali-metal atoms in optical tweezers. Our low atom loss and high-fidelity state detection eliminates the extra depumping mechanism due to population transfer between excited-state sublevels through V-type stimulated Raman transitions caused by the trap laser when the probe laser is present. In this work, complex optical systems and stringent vacuum pressures are not required.
