He invented an entirely new technology—the "logic clock." It is the world's most accurate atomic clock with an uncertainty equivalent to one second in 4 billion years and continually improving. Logic clocks can be used for exquisitely sensitive measurements of gravity, motion, and other quantities, exploiting the "ticking rate" to make a new class of sensors which can be used in mineral exploration, inertial navigation and new ultra-precise measurements of fundamental physics constants.
