Researchers in Boulder built a new clock that is more precise and accurate than any clock in the world. The discovery has implications for exploring fundamental physics questions, propelling new ...
By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in ...
A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known as NIST-F4, ...
In this case, the new clock uses an ion of aluminum linked to an ion of magnesium, forming what is known as a quantum logic clock. In this, the aluminum ion has a high-frequency, stable "tick." ...
