Abstract: Is gravity quantum mechanical? If so, we argue that nonlinear effects in black hole ringdowns—notably second harmonic generation—generates gravitational waves in non-classical states. While quantum features of these states such as sub-Poissonian statistics or entanglement… read more here.
