量子时钟同步算法的核磁共振实现

Nuclear Magnetic Resonance Implementation of a Quantum Clock Synchronization Algorithm

Jingfu Zhang, Guilu Long, Zhiwei Deng, Wenzhang Liu, Zhiheng Lu

摘要:

提出的量子时钟同步算法。L. Chuang(Phys.Rev.Lett,85,2006(2000))已经在三量子位核磁共振量子系统中实现。用空间平均法制备了有效纯态。两个分离的时钟之间的时间差可以通过NMR光谱直接读出来确定。

英文摘要:

The quantum clock synchronization algorithm proposed by I. L. Chuang (Phys. Rev. Lett, 85, 2006(2000)) has been implemented in a three qubit nuclear magnetic resonance quantum system. The effective-pure state is prepared by the spatial averaging approach. The time difference between two separated clocks can be determined by reading out directly through the NMR spectra.
