There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped ...

Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the ...

Illustration of the ion trap that forms the heart of NIST's quantum logic clock. The trap is the gold structure with the cross-shaped cutout. The inset shows the aluminum ion (blue), the source of the ...

The steady tick of a clock usually feels simple and dependable. Something swings or vibrates in a controlled rhythm and marks the passing of each moment. What you rarely notice is the hidden cost ...

Researchers at the U.S. National Institute of Standards & Technology (NIST) say they have created the most accurate atomic clock to date — one that can measure time down to the 19th decimal place.

Quantum technologies—devices that operate according to quantum mechanical principles—promise to bring users some groundbreaking innovations in whichever context they appear. Ironically, the same ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.
