We propose a general framework that yields useful lower bounds for ultimate limits of precision in parameter estimation for noisy systems, and describes the transition from the Heisenberg to the standard limit in optical interferometry

This tutorial reviews a general method of parameter estimation for noisy systems, which leads to useful bounds on the precision in optical interferometry, weak-force measurement, and the time duration of physical processes.
