Quantum timekeeping

Physicists are exploring the mind-blowing possibilities of linking a new generation of atomic clocks

QUANTUM TIMEKEEPING  Atomic clocks are so precise that physicists can measure time to the quintillionth (10-18) of a second with confidence. An entangled clock could do even better.
