The foundations of physics is proposed to be quantum information and a duality between spacetime observables and quantum fields. This is a form of the standard AdS/CF T correspondence and the Ryu-Takayanagi formula [1]. Quantum gravity and quantum hair on event horizons is shown can be detected in black hole coalescence. The near horizon condition for two black holes right before collision is a deformed AdS spacetime RT entropy given by quantum hair on the horizons. These qubits may appear in gravitational wave data. The RT formula and its relationship to the Mirzakhani entropy formula [2] suggests a complementarity between quantum and spacetime observables.
