| 摘 要： | 利用一种优化的幺正算符制备了一种高度纠缠态--cluster 态，这个优化的幺正算符因为只需要施加非选择性脉冲，其所用的时间被明显缩短．该文选择一个三量子位的自旋体系，在核磁共振仪器上进行了实验验证，实验过程中先制备了一个三量子位的纯态，然后通过施加优化的幺正算符即可得到三量子位的cluster 态，实验结果证明了优化幺正算符的有效性．

| Abstract: | This paper exploits one optimized unitary operator to prepare a type of highly entangled state of multiple qubits-cluster state. Based on optimal control theory, the duration of optimized unitary operator has been shortened due to the application of a series of non-selective pulse. We experimentally implemented the optimized unitary operator on a NMR spectrometer. By firstly generating a pseudo-pure state, a three-qubit cluster state was produced by applying the optimized unitary operator. Our experimental results show the feasibility of the optimized unitary operator. |
