Universal Set of Gates for Microwave Dressed-State Quantum Computing
  We propose a set of techniques that enable universal quantum computing to be carried out using dressed states. This applies in particular to the effort of realising quantum computation in trapped ions using long-wavelength radiation, where coupling enhancement is achieved by means of static magnetic-field gradient. We show how the presence of dressing fields enables the construction of robust single and multi-qubit gates despite the unavoidable presence of magnetic noise, an approach that can be generalised to provide shielding in any analogous quantum system that relies on the coupling of electronic degrees of freedom via bosonic modes.
