振动分子中的干涉条纹是量子力学的一个特征，但它们往往是如此短暂和紧密，以至于无法可视化。我们已经实验可视化的动态量子干涉，出现和消失在不到100飞秒的碘分子同步的两个反向传播的核波包的周期性交叉。所获得的图像具有皮米和飞秒时空分辨率，代表了量子干涉的详细图像。
Interference fringes in vibrating molecules are a signature of quantum mechanics, but are often so short-lived and closely spaced that they elude visualization. We have experimentally visualized dynamical quantum interferences, which appear and disappear in less than 100 femtoseconds in the iodine molecule synchronously with the periodic crossing of two counterpropagating nuclear wave packets. The obtained images have picometer and femtosecond spatiotemporal resolution, representing a detailed picture of the quantum interference.
