- Funded by EPSRC-funded UK Quantum Communications hub and the Innovation Fund Denmark, this paper was the first work to show that quantum teleportation can be used as a basic tool to simplify the adaptive structure of the most general protocols of quantum metrology. By setting the ultimate precision limits of parameter estimation and channel discrimination, the work has had broad implications, from quantum sensing to imaging and metrology. It has led to a better understanding of the negative influence of noise in degrading the performance of quantum metrological tasks, limiting the estimation of noise to the so-called standard quantum limit.
