‘Quantum Logic Clock’ May Be World’s Most Accurate Clock

March 10th, 2008

An atomic clock that uses an aluminum atom to apply the logic of computers to the peculiarities of the quantum world now rivals the world’s most accurate clock, based on a single mercury atom. Both clocks are at least 10 times more accurate than the current U.S. time standard.

These clocks were observed for a year long process and built by the Commerce Department’s National Institute of Standards and Technology (NIST). The tests allowed scientists to measure the relative frequencies of the two clocks to 17 digits-the most accurate measurement of this type ever made. These results produced the most accurate results of time keeping of any other method in history.

The actual construction and science behind these tests and the clocks can be found here in a more detailed analysis.

IS it more accurate than the Death Clock? Surely this franchise is going to have to make some changes after this test…lol
