Innovations in Gravitational Wave Detection Technology

A method has been proposed to project gravitational wave signals onto phase-sensitive entangled states using orbital atomic sensors in quantum squeezed states. Simulation results indicate that this technology can enhance the detection sensitivity of existing LIGO quantum noise by about an order of magnitude and increase the detection volume by about three orders of magnitude in key frequency ranges, significantly enhancing the potential for gravitational wave detection in the study of dark matter and black holes.
