Nuclear Magnetic Resonance Implementation of a Quantum Clock Synchronization Algorithm
arXiv:quant-ph/0406208 · doi:10.1103/PhysRevA.70.062322
Abstract
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.
