DESCRIPTION:Quantum control of large spin registers is crucial for many app
 lications ranging from spectroscopy to quantum information. A key factor t
 hat determines the efficiency of a register for implementing a given infor
 mation processing task is its network topology. One particular type\, call
 ed star-topology\, involves a central qubit uniformly interacting with a s
 et of ancillary qubits. A particular advantage of the star-topology quantu
 m registers is in the efficient preparation of large entangled states\, ca
 lled NOON states\, and their generalized variants. Thanks to the robust ge
 neration of such correlated states\, spectral simplicity\, ease of polariz
 ation transfer from ancillary qubits to the central qubit\, as well as the
  availability of large spin-clusters\, the star-topology registers have be
 en utilized for several interesting applications over the last few years. 
 Here we review some recent progress with the star-topology registers\, par
 ticularly via nuclear magnetic resonance methods.
