Quantifying quantum-amplified metrology via Fisher information
We present a unified framework, based on quantum metrology concepts, for defining and quantifying deterministic noiseless quantum amplification of parameter-dependent processes, which plays an important role in increasing the precision of quantum sensing. Recent experiments [Burd et al., Science 364...
