论文摘要
我们基于线性表面陷阱的二维布置提出了一个离子晶格量子处理器。我们的设计具有相邻晶格位点的离子之间的可调耦合和可配置的离子晶体连接性，例如，例如，一个具有相同陷阱芯片的矩形和三角形晶格。我们介绍了最简单的离子阵列的详细陷阱模拟，并带有$ 2 \ times9 $捕获站点，并报告在工业设施中制造原型设备的制造。设计和使用的制造过程可扩展到较大的阵列尺寸。我们证明了离子在矩形和三角形晶格中的捕获，并在一个晶格期间展示了$ 2 \ times2 $ ion晶格的运输。
We present an ion-lattice quantum processor based on a two-dimensional arrangement of linear surface traps. Our design features a tunable coupling between ions in adjacent lattice sites and a configurable ion-lattice connectivity, allowing one, e.g., to realize rectangular and triangular lattices with the same trap chip. We present detailed trap simulations of a simplest-instance ion array with $2\times9$ trapping sites and report on the fabrication of a prototype device in an industrial facility. The design and the employed fabrication processes are scalable to larger array sizes. We demonstrate trapping of ions in rectangular and triangular lattices and demonstrate transport of a $2\times2$ ion-lattice over one lattice period.
