我们演示了在光镊中相干产生单个NaCs分子的旋转、振动和电子（旋振）基态。从弱束缚的Feshbach分子出发，通过垂直棒c（3）Sigma（1），v“= 26 >激发态定位了一个双光子跃迁，并驱动了Feshbach态与NaCs旋振基态垂直棒X-1 Sigma，v "= 0的单个超精细能级之间的相干Rabi振荡; N "= 0 >，结合能为D-0 = h x 147044.63（11）GHz。我们测量的寿命为3.4 +/- 1.6秒的旋转振动基态分子，它具有一个大的分子框架的偶极矩为4.6D，占据了主要的运动基态。这些长寿命的、完全量子态控制的单个偶极分子为基于分子的量子模拟和信息处理提供了关键资源。
We demonstrate the coherent creation of a single NaCs molecule in its rotational, vibrational, and electronic (rovibronic) ground state in an optical tweezer. Starting with a weakly bound Feshbach molecule, we locate a two-photon transition via the vertical bar c(3)Sigma(1), v' = 26 > excited state and drive coherent Rabi oscillations between the Feshbach state and a single hyperfine level of the NaCs rovibronic ground state vertical bar X-1 Sigma; v '' = 0; N '' = 0 > with a binding energy of D-0 = h x 147044.63(11) GHz. We measure a lifetime of 3.4 +/- 1.6 s for the rovibronic ground state molecule, which possesses a large molecule-frame dipole moment of 4.6D and occupies predominantly the motional ground state. These long-lived, fully quantum-state-controlled individual dipolar molecules provide a key resource for molecule-based quantum simulation and information processing.
