Theoretical Foundations for Design of a Quantum Wigner Interferometer
Marco O. Lanzagorta, Jeffrey K. Uhlmann · IEEE Journal of Quantum Electronics · 2018
In this paper, we discuss and analyze a new quantum-based approach for gravimetry. The key feature of this design is that it measures effects of gravitation on information encoded in qubits in a way that can provide resolution beyond the de Broglie limit of atom-interferometric gravimeters. We show that it also offers an advantage over current state-of-the-art gravimeters in its ability to detect quadrupole field anomalies. This can potentially facilitate applications relating to search and recovery, e.g., locating a submerged aircraft on the ocean floor, based on the difference between the specific quadrupole signature of the object of interest and that of other objects in the environment.
