Operational Meaning of Dynamical Total Coherence in Single-Parameter Quantum Channel Estimation

We establish the rigorous operational meaning of dynamical total coherence within the resource non-increasing (RNI) framework for the task of single-parameter quantum channel estimation. By connecting distance-based and maximal-increment-based dynamical coherence measures with the right-logarithmic-derivative (RLD)...
