Abstract Cold atoms and polar molecules have long been candidates for the implementation of quantum information processing. Although many schemes of two-dimensional (2D) moving optical or magnetic lattices have been proposed for atomic shift register, little work has been done on 2D electric lattice for molecular shift register, mainly due to the complexity of molecular energy level structures as well as the challenge to build micropotentials that are scalable, smoothly moving and accurately controlled. Here we present a design of chip-based 2D electric lattice for molecular shift register capable of scaling and controlling, which mainly consists of arrays of equidistant gold electrodes for generating a moving electric lattice. Our theoretical analysis and trajectory calculations, based on the polar molecules ammonia-D3 (ND3) and methylidyne radical (CH), show explicitly that the 2D lattice is able to directly slow down arrays of polar molecules from supersonic speeds to a standstill over a distance of a few centimeters, and then hold them for a certain time or shift them back in a smooth manner. Besides, it also enables decelerating and trapping of the two molecular species simultaneously, which contributes to the understanding towards new phenomena such as novel quantum mechanical collisions and cold chemistry.

用于极性分子的芯片上可扩展的二维移动电晶格

摘要 冷原子和极性分子长期以来一直是实现量子信息处理的候选对象。尽管已经提出了许多用于原子移位寄存器的二维（2D）移动光或磁晶格的方案，但在用于分子移位寄存器的二维电晶格方面的工作很少，主要是由于分子能级结构的复杂性以及构建可扩展、平稳移动和精确控制的微电位的挑战。在这里，我们提出了一种用于能够缩放和控制的分子移位寄存器的基于芯片的二维电晶格的设计，其主要由用于产生移动电晶格的等距金电极阵列组成。我们的理论分析和轨迹计算，基于极性分子氨-D3 (ND3) 和甲基炔基 (CH)，明确表明二维晶格能够直接将极性分子阵列从超音速减慢到几厘米距离内的静止状态，然后将它们保持一段时间或以平稳的方式将它们移回。此外，它还可以同时减速和捕获两种分子，这有助于理解新现象，如新的量子力学碰撞和冷化学。
