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