Signal estimation and coherence

Laura Ares et al.

Summary: We investigate the relationship between quantum metrological resolution and quantum coherence by developing a quantum version of the Wiener-Khintchine theorem for a quantum ruler model, with a focus on probe and measurement contributions. This approach is demonstrated through examples of linear metrology.
