论文以溶于重水的胞嘧啶中的两个氢的核自旋作为量子比特,直接从热平衡态开始进行Arvind算法,得到了预期结果;在同核系统中实验实现了Arvind 算法.谱图中线形扭曲和误差主要是由于频偏效应和选择脉冲的不完美.了解和发展在同核系统中实现核磁共振量子计算的技术,将有助于我们实验实现需要多个比特的量子计算,更好的理解量子计算.
論文以溶于重水的胞嘧啶中的兩箇氫的覈自鏇作為量子比特,直接從熱平衡態開始進行Arvind算法,得到瞭預期結果;在同覈繫統中實驗實現瞭Arvind 算法.譜圖中線形扭麯和誤差主要是由于頻偏效應和選擇脈遲的不完美.瞭解和髮展在同覈繫統中實現覈磁共振量子計算的技術,將有助于我們實驗實現需要多箇比特的量子計算,更好的理解量子計算.

Recently Arvind and Mukunda have given a quantum algorithm distinguishing the odd and even nature of a given binary function, which do not need to prepare a pseudo-pure state and need only one experiment to get the output. Preparing a pseudo-pure state costs a lot; so bypassing it is very meaningful for NMR quantum computation. The algorithm was implemnted on a two-hydrogen homonuclear spin system with the expected result, which confirmed the algorithm experimentally.
