Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future standard for measuring time.

NavIC satellite lost its last working atomic clock within minutes, raising concerns about accuracy. (Image: Canva) Atomic clock failure hits IRNSS-1F satellite in NavIC system. Repeated clock issues ...

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 ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

The most precise clocks ever built are now testing Einstein, hunting dark matter, and reshaping how we define time itself. The world’s most precise clocks are changing how we understand time itself: ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...

Atomic clocks have long served as the benchmark for precise timekeeping by utilising the stable frequency of atomic transitions as a reference. Recent developments focus on harnessing coherent ...

Bengaluru: India’s domestic navigation system, NavIC, has officially ceased operations after the number of functional satellites in its constellation dropped below the critical threshold required for ...

Unlike other atoms (left), ytterbium-173 (right) has a large nuclear spin and a strongly deformed nucleus whose strong fields interact with the electron shell. This turns forbidden quantum jumps into ...

BOULDER • Every second in a small laboratory room in Boulder, a green light flashes. Within the webs of yellow wire and shelves of computer systems, this green light represents the passage of time.

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...
