Query: Generation of spin-motion entanglement in a trapped ion using
  long-wavelength radiation   Applying a magnetic field gradient to a trapped ion allows long-wavelength
microwave radiation to produce a mechanical force on the ion's motion when
internal transitions are driven. We demonstrate such a coupling using a single
trapped \Yb{171}~ion, and use it to produce entanglement between the spin and
motional state, an essential step towards using such a field gradient to
implement multi-qubit operations.
