Abstract

We present a description of multidimensional spectroscopy, where all the light pulses are treated quantum-mechanically and the signal is expressed as a quantum dynamical map of the broadband light fields. Focusing in particular on the rephasing contribution to two-dimensional spectroscopy, we demonstrate how the semiclassical description emerges naturally as a limiting case of the quantum description. Our work establishes a formalism to apply quantum information methods to the optimization of multidimensional spectroscopy and address, e.g., fundamental resolution limits from a quantum metrological perspective.

多维光谱的量子电动力学公式。

我们提出了一种多维光谱的描述，其中所有的光脉冲都被量子力学处理，信号被表示为宽带光场的量子动态图。特别关注重相位对二维光谱学的贡献，我们展示了半经典描述如何作为量子描述的极限情况自然出现。我们的工作建立了一种将量子信息方法应用于多维光谱优化的形式体系，并从量子计量的角度解决了基本分辨率限制等问题。
