Quantum Interferometry

Quantum interferometry involves using the wave-like properties of particles, such as atoms or photons, to measure minute changes in physical quantities like gravity, time, or motion. By splitting a quantum particle's wavefunction into multiple paths and then recombining them, interference patterns emerge that are extremely sensitive to tiny differences along those paths. These patterns allow scientists to detect incredibly small variations—far beyond traditional measurement methods—making quantum interferometry a powerful tool for precision sensing in fundamental physics, navigation, and Earth studies.
