Gravitational Wave Communication via Correlated Photon Tunneling Events in Optical Fiber Ring Resonators Arising from Hyperentangled Photon Pairs

A laboratory Hertz-like gravitational wave communication system (“gravity radio”) is proposed using coherent optical-stress sources in high-Q optical fiber ring-resonator arrays. Hyperentangled photon pairs and coincident tunneling events provide timing, phase, and correlations, while the gravitational source is the local, conserved field-plus-medium stress-energy tensor generated by phase-locked coherent optical fields. Because the electromagnetic stress tensor is quadratic in the fields, the source can contain both sum-frequency and difference-frequency components. The latter is emphasized because it relaxes the localization, phase-stability, and receiver-transduction requirements. The directed coherent transverse-traceless stress amplitude and receiver equivalent strain noise are derived for a meter-scale transfer test.
