Approaching the optimum phase measurement in the presence of amplifier noise
Darko Zibar, Jens E. Pedersen, Poul Varming +2
In fundamental papers from 1962 [1, 2], Heffener and Haus showed that it is not possible to construct a linear noiseless amplifier. The implies that the amplifier intrinsic noise s…
