论文摘要
高自旋磁分子是量子信息处理的有前途的候选者，因为它们本质上具有多个用于信息存储和计算操作的差异。但是，由于它们对环境的敏感性和选择规则的限制，因此尚未实现对分子和电子自旋基础的多级系统量子状态的任意控制。在这里，我们将C70的光激发三重态作为分子电子旋转Qutrit。在通过光激发初始化系统后，我们将其准备成代表性的三级叠加态的特征，测量了其密度矩阵，并显示了叠加中量子相的干扰。干扰模式进一步解释为在不同条件下时间通过时间的进化图。
High spin magnetic molecules are promising candidates for quantum information processing because they intrinsically have multiple sublevels for information storage and computational operations. However, due to their susceptibility to the environment and limitation from the selection rule, the arbitrary control of the quantum state of a multilevel system on a molecular and electron spin basis has not been realized. Here we exploit the photoexcited triplet of C70 as a molecular electron spin qutrit. After the system was initialized by photoexcitation, we prepared it into representative three-level superposition states characteristic of the qutrit, measured their density matrices, and showed the interference of the quantum phases in the superposition. The interference pattern is further interpreted as a map of evolution through time under different conditions.
