Quantum sensing of weak radio-frequency signals by pulsed Mollow absorption spectroscopy

Quantum sensing of weak radio-frequency signals by pulsed Mollow absorption spectroscopy

Dynamical decoupling protocols can enhance the sensitivity of quantum sensors but this is limited to signal frequencies below a few MHz. Here, Joas et al. use the Mollow triplet splitting in a nitrogen-vacancy centre to overcome this limitation, enabling sensitive detection of signals in the GHz ran...
