For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

Atomic clocks, which power GPS, online transactions, and data networks, just became more precise. MIT physicists have developed a technique that doubles the accuracy of optical atomic clocks by ...

For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ...

A power outage on Dec. 19 at the National Institute of Standards and Technology (NIST) campus in Boulder, Colo., disrupted operation of the NIST-F4 atomic clock. Hurricane force winds and dry ...

Claire Cramer, the executive director of quantum science at the University of California, Berkeley, who was in attendance, expressed optimism about the potential of solid-state nuclear clocks: “This ...
