- Abstract: We present a quantum sensing technique that utilizes a sequence of $\pi$
pulses to cyclically drive the qubit dynamics along a geodesic path of
adiabatic evolution. This approach effectively suppresses the effects of both
decoherence noise and control errors while simultaneously removing unwanted
resonance terms, such as higher harmonics and spurious responses commonly
encountered in dynamical decoupling control. As a result, our technique offers
robust, wide-band, unambiguous, and high-resolution quantum sensing
capabilities for signal detection and individual addressing of quantum systems,
including spins. To demonstrate its versatility, we showcase successful
applications of our method in both low-frequency and high-frequency sensing
scenarios. The significance of this quantum sensing technique extends to the
detection of complex signals and the control of intricate quantum environments.
By enhancing detection accuracy and enabling precise manipulation of quantum
systems, our method holds considerable promise for a variety of practical
applications.
