Paper on the optimality of quantum enhancement in the GEO600 gravitational wave detector published
It is theoretically demonstrated that the recently reported quantum-noise-limited sensitivity of the squeezed-light-enhanced German-British gravitational wave detector GEO 600 is exceedingly close to the fundamental theoretical bound, given the present amount of optical loss. Furthermore, it is proven that the employed combination of a bright coherent state and a squeezed vacuum state is generally the optimum practical approach for phase estimation with high precision on absolute scales.
