Liquid Nuclear Magnetic Resonance Implementation of Quantum Computation in Subspace 总被引:1,自引:0,他引:1 下载免费PDF全文
Based on the logical labelling method, we prepare an effective pure state in a subsystem of a three spin system via liquid nuclear magnetic resonance technique. Then with this subspace effective pure state we implement the Deutsch-Jozsa algorithm. The tomography for the subspace effective pure state and the corresponding spectrum of the output for the Deutsch-Jozsa algorithm agree with theoretical predictions, which shows that we have successfully implemented the Deutsch-Jozsa algorithm in a subsystem of a nuclear spin system and demonstrated a subspace quantum computation. 相似文献

Zr基金属玻璃电子输运性质的研究 总被引:2,自引:0,他引:2
在4—300K 的温度区间内,测量了金属玻璃 Zr_(100-x)Co_x(x=22,28,33.2)和Zr_(66.7)M_(33.3)(M=Fe,Ni,Cu)的电阻温度关系.实验指出,这两组典型的 Zr 基金属玻璃的电子输运性质,有着共同的规律性.分析表明,在10K80K 时,这种规律与现有的理论有较大的偏离,对这种偏离出现的可能起因作了讨论. 相似文献
