Until recently, such a sensor \u2014 a thousand times more sensitive than today\u2019s navigation-grade devices \u2014 would have filled a moving truck. But advancements are dramatically shrinking the size and cost of this technology.<\/p>\n<p>For the first time, researchers from Sandia National Laboratories have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It is the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Peel apart a smartphone, fitness tracker or virtual reality headset, and inside you\u2019ll find a tiny motion sensor tracking its position and movement.
