Ultra-Precise Chip-Scale Atomic Clocks for Next-Generation Navigation and Timing

digitalPrototypeTRL 3

Imagine shrinking a room-sized, super-accurate clock down to the size of a computer chip. This technology uses light instead of radio waves to keep time, making it far more precise. It's like moving from a ticking wall clock to a digital stopwatch that never loses a billionth of a second.
