摘要：

The input states of an interferometer have been optimized at fixed total photon number N and quantum efficiency eta. I show that the phase sensitivity is bounded by Delta phi similar to N--3/4 for a coherent input signal and by Delta phi similar to N-1 for squeezed optimized inputs. I also show that in actual non-efficient interferometers only little squeezing is needed to reach the best sensitivity.
