An optical lattice clock is a type of atomic clock that can be 100 times more accurate than cesium atomic clocks, the current standard for defining "seconds." Its precision is equivalent to an ...

Accurate frequency measurements of a narrow optical clock transition in 171 Yb atoms trapped in an optical lattice establish this system as a serious contender in the quest to develop increasingly ...

Japanese precision equipment maker Shimadzu Corp said Wednesday that it has begun selling an optical lattice clock with a deviation of less than one second over 10 billion years, making it the most ...
