    "abstract": "We report the implementation of the central building block of the\nSchulman-Vazirani procedure for fully polarizing a subset of two-level quantum\nsystems which are initially only partially polarized. This procedure consists\nof a sequence of unitary operations and incurs only a quasi-linear overhead in\nthe number of quantum systems and operations required. The key building block\ninvolves three quantum systems and was implemented on a homonuclear three-spin\nsystem using room temperature liquid state nuclear magnetic resonance (NMR)\ntechniques. This work was inspired by the state initialization challenges in\ncurrent NMR quantum computers but also shines new light on polarization\ntransfer in NMR.",
