Jean and Arne's paper "Hybrid continuous dynamical decoupling: a photon-phonon doubly dressed spin" studies parametric interaction between a single Nitrogen-Vacancy electronic spin and a diamond mechanical resonator. We present a novel dynamical decoupling scheme, which is based on recently established techniques for dynamical decoupling by concatenated continuous driving. Our work benefits from a robust, drift-free strain-coupling mechanism we have established in the past and from the narrow linewidth of the high-quality diamond mechanical oscillator we employ. We demonstrate prolongation of the relevant spin dephasing times by up to two orders of magnitude, suggesting feasible applications of our decoupling scheme in quantum information processing and sensing.
