Our scientific objective is to pioneer innovative methods for observing gravitational waves at low frequencies, leveraging the unique astronomical gravitational wave (GW) signature. As gravitational waves traverse the Earth, they induce a minuscule yet coordinated apparent motion among all celestial bodies. Our groundbreaking approach utilizes high-precision astronomical measurements through quantum mechanical two-photon interference, a technique recently unveiled. This method offers the notable advantage of enabling two separate interferometric spacecraft stations to function autonomously, without optical connections, simplifying spacecraft design compared to traditional space-based interferometer configurations. This capability empowers us to detect gravitational waves in the micro- to nano-Hz frequency range with extraordinary sensitivity—essentially filling a significant gap as current alternatives for detecting GWs in this band are nonexistent. We outline how this ambitious mission can be realized with two modestly sized spacecraft in free-fall orbits. Detecting these gravitational waves would profoundly enhance our understanding of galaxy formation and supersymmetric black holes, while also captivating public interest.
