Query: NMR implementation of a building block for scalable quantum computation   We report the implementation of the central building block of the
Schulman-Vazirani procedure for fully polarizing a subset of two-level quantum
systems which are initially only partially polarized. This procedure consists
of a sequence of unitary operations and incurs only a quasi-linear overhead in
the number of quantum systems and operations required. The key building block
involves three quantum systems and was implemented on a homonuclear three-spin
system using room temperature liquid state nuclear magnetic resonance (NMR)
techniques. This work was inspired by the state initialization challenges in
current NMR quantum computers but also shines new light on polarization
transfer in NMR.
