    "abstract": "We describe the creation of a Greenberger-Horne-Zeilinger (GHZ) state of the\nform |000\u003e+|111\u003e (three maximally entangled quantum bits) using Nuclear\nMagnetic Resonance (NMR). We have successfully carried out the experiment using\nthe proton and carbon spins of trichloroethylene, and confirmed the result\nusing state tomography. We have thus extended the space of entangled quantum\nstates explored systematically to three quantum bits, an essential step for\nquantum computation.",
