论文摘要

与纠缠相关的基本挑战阻止了基于量子干扰的控制(即相干控制)碰撞横截面在实验室中实施。在这里,显示低温下反应性散射的差分横截面可提供独特的机会,通过形成不同m的反应剂分子的退化旋转状态的相干叠加来显示这种基于干扰的控制。特别是,我们在反应性散射中识别并量化了与F + H2的应用相干控制的独特签名! H + HF和HF + D F + HD! 11 K时的HD +F。对照显示为广泛。

Fundamental entanglement related challenges have prevented quantum interference-based control (i.e. coherent control) of collisional cross sections from being implemented in the laboratory. Here, differential cross sections for reactive scattering at low temperatures are shown to provide a unique opportunity to display such interference-based control by forming coherent superpositions of degenerate rotational states of reactant molecules |jmi with different m. In particular, we identify and quantify a unique signature of coherent control in reactive scattering with applications to F + H2 ! H + HF and HF + D F + HD ! HD + F at 11 K. Control is shown to be extensive.
