Universal set of gates for microwave dressed-state quantum computing

Abstract: 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 realizing 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 generalized to… Show more

“…Single-qubit gates using the dressed states ñ | as a qubit can be carried out by employing a resonant RF-field [35][36][37]. In order to implement conditional quantum gates, for example 2-qubit gates, the application of an RF-field tuned (close) to resonance with a motional sideband transition between dressed states can be used [1,17,22,38,39]. In this case, the effective Lamb-Dicke parameter j n , e allows for the necessary coupling between qubit states and motional states [10].…”
