Schematic of a laser interferometer used to observe gravitational waves. If the quantum uncertainty of the radiation pressure of the light is the dominant dynamic force acting on the mirrors, a common quantum object arises from the mirror and the reflected light beam. In this case, the sensitivity of the interferometer is optimal when measuring changes in mirror positions due to gravitational waves.
