用核磁共振方法模拟了一维原子链上激发的传播。用作模拟量子计算机的物理系统是液晶矩阵中的133-Cs（自旋7/2）核。利用一个特殊的7频脉冲模拟了迁移的哈密顿量，并通过跟踪种群从8个自旋能级中的一个能级到另一个能级的转移来监测动力学。
The propagation of excitation along a one-dimensional chain of atoms is simulated by means of NMR. The physical system used as an analog quantum computer is a nucleus of 133-Cs (spin 7/2) in a liquid crystalline matrix. The Hamiltonian of migration is simulated by using a special 7-frequency pulse, and the dynamics is monitored by following the transfer of population from one of the 8 spin energy levels to the other.
