# Noise-robust quantum sensing via optimal multi-probe spectroscopy

@article{Mller2018NoiserobustQS, title={Noise-robust quantum sensing via optimal multi-probe spectroscopy}, author={Matthias M. M{\"u}ller and Stefano Gherardini and Filippo Caruso}, journal={Scientific Reports}, year={2018}, volume={8} }

The dynamics of quantum systems are unavoidably influenced by their environment, but in turn observing a quantum system (probe) can allow one to measure its environment: Measurements and controlled manipulation of the probe such as dynamical decoupling sequences as an extension of the Ramsey interference measurement allow to spectrally resolve a noise field coupled to the probe. Here, we introduce fast and robust estimation strategies for the characterization of the spectral properties of…
