Query: Fast, low-power manipulation of spin ensembles in superconducting
  microresonators   We demonstrate the use of high-Q superconducting coplanar waveguide (CPW)
microresonators to perform rapid manipulations on a randomly distributed spin
ensemble using very low microwave power (400 nW). This power is compatible with
dilution refrigerators, making microwave manipulation of spin ensembles
feasible for quantum computing applications. We also describe the use of
adiabatic microwave pulses to overcome microwave magnetic field ($B_{1}$)
inhomogeneities inherent to CPW resonators. This allows for uniform control
over a randomly distributed spin ensemble. Sensitivity data are reported
showing a single shot (no signal averaging) sensitivity to $10^{7}$ spins or $3
\times 10^{4}$ spins/$\sqrt{Hz}$ with averaging.
