"6 thin lasers pin cloud of 10s of 1,000s rubidium atoms in place at few billionths degree above absolute zero forming Bose-Einstein Condensate, next, jiggle atoms using laser light so each atom superpositions so simultaneously in 2 places at once. each part following different path... when parts nap back together form unique pattern indicating acceleration experienced, based on multi-step laser adjustments guided by machine learning... precise navigation of vehicles such as cars, submarines, spacecraft"
