Robust quantum noise detection

This paper demonstrates a new measurement scheme that enables characterization of incoherent quantum noise while reducing the impact of coherent control errors. Experiments on a diamond nitrogen-vacancy system under controllable noise conditions exhibit improved robustness in quantifying dephasing time. This approach helps distinguish between coherent and incoherent errors to support advances in quantum technologies.
