Modern de Broglie wave interferometers separate atomic wavepackets by 0.5 m for times of 2 sec. This lecture will discuss the science and technology implications of these results, and describe the techniques employed to realize these instruments. Applications range from high resolution satellite geodesy to gravitational wave detection and test of quantum mechanics.
