Not satisfied with the accuracy of the "quantum logic clock" (which only gains or loses one second every 3.7 billion years), the National Institute of Standards and Technology (NIST) and JILA have ...
Heralding a new age of terrific timekeeping, physicists have unveiled an experimental strontium atomic clock that has set new world records for both precision and stability -- key metrics for the ...
The JILA strontium lattice clock is about 50 percent more precise than the record holder of the past few years, NIST’s quantum logic clock. Precision refers to how closely the clock approaches the ...
