论文摘要
携带旋转分子是量子技术的有希望的构建块，因为它们可以化学调节，组装成可扩展的阵列，并很容易地将其掺入各种设备架构中。在分子系统中，光学处理地面旋转将在量子信息科学中实现广泛的应用，这已证明是固态缺陷。但是，对于分子而言，这种重要的功能仍然难以捉摸。在这里，我们在一系列合成的有机金属铬（IV）分子中证明了这种光学通讯性。这些化合物显示了一个基态自旋，可以使用光初始化并读出，并用微波炉连贯地操纵。另外，通过对分子结构的原子修饰，我们调整了这些化合物的自旋和光学特性，为从自下而上的设计器量子系统铺平了道路。
Spin-bearing molecules are promising building blocks for quantum technologies as they can be chemically tuned, assembled into scalable arrays, and readily incorporated into diverse device architectures. In molecular systems, optically addressing ground-state spins would enable a wide range of applications in quantum information science, as has been demonstrated for solid-state defects. However, this important functionality has remained elusive for molecules. Here, we demonstrate such optical addressability in a series of synthesized organometallic, chromium(IV) molecules. These compounds display a ground-state spin that can be initialized and read out using light, and coherently manipulated with microwaves. In addition, through atomistic modification of the molecular structure, we tune the spin and optical properties of these compounds, paving the way for designer quantum systems synthesized from the bottom-up.
