Condensed Matter Physics Seminar: Robust gates for microwave gates

Abstract:

A set of techniques that enable universal quantum computing to be carried out using dressed states will be described. This applies in particular to the effort of realising quantum computation experimentally in trapped ions using long-wavelength radiation. It will be shown 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.
