Improved mirror position estimation using resonant quantum smoothing

Wheatley, Trevor A; Tsang, Mankei; Petersen, Ian R; Huntington, Elanor Harriet


Quantum parameter estimation, the ability to precisely obtain a classical value in a quantum system, is very important to many key quantum technologies. Many of these technologies rely on an optical probe, either coherent or squeezed states to make a precise measurement of a parameter ultimately limited by quantum mechanics. We use this technique to theoretically model, simulate and validate by experiment the measurement and precise estimation of the position of a cavity mirror. In non-resonant...[Show more]
