论文摘要
长相干时间的分子的光学诱捕对于量子信息和计量学方面的许多方案至关重要。但是，限制捕获分子的寿命的因素仍然难以捉摸，需要提高对基本分子结构的理解。在这里，我们表明，在弱和深度绑定的$^{88} $ sr $ _2 $分子中的振动线强度的测量值与\ textit {ab libtiO}计算相结合，允许对振动量子数的明确识别。反过来，这可以构建精致的激发势能曲线，从而为魔术波长的选择提供了促进长振动连贯性的选择。我们证明了持续近100 ms的远距离振动状态之间的Rabi振荡。
Optical trapping of molecules with long coherence times is crucial for many protocols in quantum information and metrology. However, the factors that limit the lifetimes of the trapped molecules remain elusive and require improved understanding of the underlying molecular structure. Here we show that measurements of vibronic line strengths in weakly and deeply bound $^{88}$Sr$_2$ molecules, combined with \textit{ab initio} calculations, allow for unambiguous identification of vibrational quantum numbers. This, in turn, enables the construction of refined excited potential energy curves that inform the selection of magic wavelengths which facilitate long vibrational coherence. We demonstrate Rabi oscillations between far-separated vibrational states that persist for nearly 100 ms.
