New measurement scheme mitigates coherent errors when quantifying incoherent noise

Helps distinguish between coherent vs incoherent errors to advance quantum tech
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.
