Microwave quantum heterodyne sensing using a continuous concatenated dynamical decoupling protocol

Abstract By sequentially recording the phase of an AC signal relative to an external clock, quantum heterodyne schemes have recorded MHz and GHz signals with Fourier-limited precision. However, in systems with large inhomogeneous broadening, existing heterodyne protocols provide limited protection o...
