interferometry is the experimental technique of splitting, manipulating, and recombining the quantum wavefunction of massive particles to measure phase differences that reveal forces, potentials, or quantum properties.<\/p>\n\n\n\n<p>Analogy: like dropping two pebbles in a pond at different spots, letting the ripples meet, and inferring the disturbance that happened to one ripple from the pattern where they recombine.<\/p>\n\n\n\n<p>Formal technical line: interference of de Broglie matter waves observed via phase-sensitive recombination of coherent particle states.<\/p>\n\n\n\n<hr
