对于许多利用丰富的状态空间和分子内在相互作用的量子科学应用来说，完全内部和运动状态控制且可单独操纵的极性分子是理想的。虽然先前通过光镊中单独捕获的组成原子组装分子的努力实现了这一目标（Zhang JT et al 2020 Phys. Rev. Lett. 124 253401；Cairncross WB et al 2021 Phys. Rev. Lett. 126 123402；He X et al 2020 Science 370 331–5），在这里，我们将该技术扩展到五个分子的阵列，解锁了研究分子相互作用的能力。我们详细介绍了扩展该系统所固有的技术挑战和解决方案。通过并行制备和控制多个分子，该平台现在可以作为利用分子的大量资源和远程偶极相互作用的起点。
Fully internal and motional state controlled and individually manipulable polar molecules are desirable for many quantum science applications leveraging the rich state space and intrinsic interactions of molecules. While prior efforts at assembling molecules from their constituent atoms individually trapped in optical tweezers achieved such a goal for exactly one molecule (Zhang JT et al 2020 Phys. Rev. Lett. 124 253401; Cairncross WB et al 2021 Phys. Rev. Lett. 126 123402; He X et al 2020 Science 370 331–5), here we extend the technique to an array of five molecules, unlocking the ability to study molecular interactions. We detail the technical challenges and solutions inherent in scaling this system up. With parallel preparation and control of multiple molecules in hand, this platform now serves as a starting point to harness the vast resources and long-range dipolar interactions of molecules.
