We calculate spin correlation functions using IBM quantum processors, accessed online. We demonstrate the rotational invariance of the singlet state, interesting properties of the triplet states, and surprising features of a state of three entangled qubits. This exercise is ideal for remote learning and generates data with real quantum mechanical systems that are impractical to investigate in the local laboratory. Students learn a wide variety of skills, including calculation of multipartite spin correlation functions, design and analysis of quantum circuits, and remote measurement with real quantum processors.

用量子计算机计算自旋相关性

我们使用在线访问的IBM量子处理器计算自旋相关函数。我们证明了单重态的旋转不变性,三重态的有趣性质以及三个纠缠量子位状态的令人惊讶的特征。该练习是远程学习的理想选择,它使用真实的量子力学系统生成数据,而在当地实验室进行研究是不切实际的。学生将学习各种各样的技能,包括计算多自旋相关函数,设计和分析量子电路以及使用实际量子处理器进行远程测量。
