The calm вода of a lake: the slightest ripple blurs the depth. In quantum sensors, noise — random jitters — generates энтропию (disorder) and kills precision. Physicists found a solution: scramble the order of events.

The compass needle trembles when a truck rumbles by. Similarly, in a tiny gyroscope, a device that senses rotation, any noise drowns out the useful signal. For a long time, engineers couldn't shrink a gyroscope down to fingernail size without sacrificing accuracy. The solution came in a two-loop architecture.
