论文摘要
量子物质合成器（QMS）是一个新的量子模拟平台，在该平台中，可以解决晶格中的单个颗粒并将其重新分配为任意模式。在空间操纵超电原子并在单粒子水平上控制其隧道和相互作用的能力可以完全控制多体量子系统。我们介绍了QM的设计和表征，该QMS集成到单个超稳定器设备中，是二维光学晶格，这是由数字微龙族设备形成的移动光学镊子阵列，以及位置分辨的原子成像。我们证明了晶格和镊子阵列之间的出色机械稳定性，相对波动以低于10 nm的波动，以2.52 kHz刷新速率对镊子阵列的高速实时控制，并以655 nm的分辨率为单位。 QM还采用了新技术和方案，例如纳米织物的抗侵蚀窗口和原子的全光距离运输。
The quantum matter synthesizer (QMS) is a new quantum simulation platform in which individual particles in a lattice can be resolved and re-arranged into arbitrary patterns. The ability to spatially manipulate ultracold atoms and control their tunneling and interactions at the single-particle level allows full control of a many-body quantum system. We present the design and characterization of the QMS, which integrates into a single ultra-stable apparatus a two-dimensional optical lattice, a moving optical tweezer array formed by a digital micromirror device, and site-resolved atomic imaging. We demonstrate excellent mechanical stability between the lattice and tweezer array with relative fluctuations below 10 nm, high-speed real-time control of the tweezer array at a 2.52 kHz refresh rate, and diffraction-limited imaging at a resolution of 655 nm. The QMS also features new technologies and schemes such as nanotextured anti-reflective windows and all-optical long-distance transport of atoms.
