实现量子控制和量子计算首先需要测定相关量子系统的哈密顿量参数信息。然而很多情况下，量子系统是不完全可测的。这里使用核磁共振量子模拟器模拟了一个三自旋的XY链模型的含时演化，通过对其中一个核自旋共振信号的读出与数据处理，成功地精确测出了该XY链的各项耦合参数信息。

To realize quantum control and quantum computation on a quantum system ,its Hamiltonian parameters must be determined first .How ever ,in many cases a quantum system is access‐limited .In our experiment ,the dynamic evolution of a 3‐spin XY chain was simulated with an NMR quantum simulator . T he Hamiltonian parameters of the 3‐spin XY chain w ere determined by measuring only the first spin and processing the data obtained .
