Abstract
The modification by noninertial motion of the photon bunching properties of an entangled biphoton state is demonstrated. Sagnac interferometers are added to both arms of a Hong-Ou-Mandel (HOM) interferometer that is mounted on a mechanically rotating platform. As the platform rotation speed is increased, HOM interference dips transform into HOM interference peaks, indicating that the entangled photons pass from perfectly indistinguishable bunching (bosonic behavior) to perfectly distinguishable antibunching (fermionic behavior).
