摘要
在魔角旋转的固体核磁共振体系中,实现了量子逻辑门.首先,利用魔角旋转去除掉样品中核间的耦合.然后,利用特殊的恢复耦合序列或者条件恢复实现量子门需要的耦合.此方法相比液体中实现量子门有较简单的序列,因为其不需要复杂的去耦序列,另外构成量子门的序列的时间也较短.最后,模拟了一系列量子门,模拟结果与理论预期一样.
Quantum gates in solid-state nuclear magnetic resonance（NMR）under magic-angle spinning（MAS）was realized.First,all anisotrope interactions of the sample were averaged out under the MAS.Then,the special pulse sequences or conditions were used to recover the interactions used to realize controlled operations.The advantage of this method for them in liquid NMR is that the pulse sequences of controlled operations are simplified,because they do not need complicated decoupling sequences,and the evolution time of the pulse sequences is shorter.Finally,the quantum operations were simulated,and the results are in complete agreement with the theoretical predictions.
