How to estimate the interaction parameter of a weak quantum measurement

There exists a shared basis for parameter estimation and the emergence of weak values: both work on the initialisation of the system, a weak interaction with a probe, and a final readout stage. However, there is no established framework encompassing this relation at the most general level. Here we establish such connections in a universal theory, and illustrate our results for the specific case of single-photon polarisation.
