项目摘要

Strongly-interacting many-body quantum states lie at the heart of phenomena such as the fractional quantum Hall effect, high-temperature superconductivity and exotic forms of magnetism. Understanding how these phenomena emerge is often computationally intractable and remains one of the great challenges of modern physics. A promising route to conquering this challenge is to use a highly controllable artificial quantum system to simulate the physics believed to underpin the behaviour observed in more complex, real materials.The goal of SimPoMol is to synthesise and study artificial quantum materials using ultracold RbCs molecules arranged in regular arrays in order to probe novel quantum phenomena in strongly interacting quantum systems. The use of molecules is motivated by their rich internal structure, combined with the existence of controllable long-range dipole-dipole interactions, long trap lifetimes and strong coupling to electric and microwave fields.We will use three experimental platforms, each leveraging our established expertise in the study of RbCs molecules, to go beyond the current state-of-the-art: bulk molecular gases, molecules assembled in arrays of optical tweezers and a quantum gas microscope for molecules in 2D optical lattices. We will engineer long rotational coherence times using rotationally-magic traps, allowing access to dipole-dipole interactions between molecules. We will exploit the rotational structure of molecules as a synthetic dimension to simulate archetypal models of topological materials and study new many-body phases in 1D chains of interacting molecules. We will demonstrate a molecular qudit encoding of the Deutsch algorithm and implement highfidelity quantum gates between molecules. Finally, we will develop single site imaging and addressing of molecules in lattices and use this powerful tool to probe the emergence of strongly correlated quantumphases and explore quantum magnetism in our artificial materials.

强烈相互交互的多体量子状态位于现象的核心，例如分数量子霍尔效应，高温超导性和磁性的外来形式。了解这些现象在计算上通常是棘手的，并且仍然是现代物理学的巨大挑战之一。征服这一挑战的有前途的途径是使用高度可控制的人造量子系统模拟被认为是在更复杂，更真实的材料中观察到的行为的物理学。Impomol的目的是使用Ultracold RBCS Molecules合成和研究人造量子材料。分子的使用是由它们丰富的内部结构的动机，再加上可控的远距离偶极双极相互作用，长陷阱寿命以及与电气和微波领域的牢固耦合。我们将使用三个实验平台，每种平台都利用了我们在RBCS分子的研究中的既有专业知识，都可以超越RBCS分子的群体：成就分子：成就分子：成就分子：成序的分子，分数：成分，分数：较高的分子，包括分子的群体：较高的分子，即成立分子，包括分子的群体。光学镊子和2D光学晶格中分子的量子气体显微镜。我们将使用旋转磁陷阱来设计较长的旋转相干时间，从而可以访问分子之间的偶极 - 偶极相互作用。我们将利用分子的旋转结构作为合成维度，以模拟拓扑材料的原型模型，并研究相互作用分子一维链中的新的多体相。我们将展示Deutsch算法的分子编码，并在分子之间实现高更额量子门。最后，我们将开发单个位点成像和晶格中分子的解决方案，并使用这种强大的工具来探测强相关的量子强调的出现，并探索我们人造材料中的量子磁性。
