Squeeze and you shall measure ? squeezed coherent states shown to be optimal for gravitational wave detection

Extremely precise measurements of distances are key in all techniques used to detect gravitational waves. To increase this precision, physicists have started using quantum effects linked with photons. A paper published in „Physical Review A” by Polish and German physicists shows that it is not necessary to use quantum light states more refined than the squeezed coherent states available currently.
