经典的光学频率梳已经彻底改变了无数领域，从光谱学和光学时钟到任意微波合成和光波通信。利用这种成熟的光学平台固有的鲁棒性和高维性，它们的非经典对应物，所谓的“量子频率梳”，最近开始显示出光纤兼容量子信息处理（QIP）和量子网络的重要前景。在这篇综述中，将涵盖频点QIP的基本理论和实验，以及对继续发展机会的展望。特别强调的是放在量子频率处理器（QFP），基于电光调制和傅里叶变换脉冲整形，能够实现高保真量子频率门在一个并行的，低噪声的方式的光子器件的最新演示。
Classical optical frequency combs have revolutionized a myriad of fields, from optical spectroscopy and optical clocks to arbitrary microwave synthesis and lightwave communication. Capitalizing on the inherent robustness and high dimensionality of this mature optical platform, their nonclassical counterparts, so-called "quantum frequency combs," have recently begun to display significant promise for fiber-compatible quantum information processing (QIP) and quantum networks. In this review, the basic theory and experiments of frequency-bin QIP, as well as perspectives on opportunities for continued advances, will be covered. Particular emphasis is placed on the recent demonstration of the quantum frequency processor (QFP), a photonic device based on electro-optic modulation and Fourier-transform pulse shaping that is capable of realizing high-fidelity quantum frequency gates in a parallel, low-noise fashion.
