Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so ...

Atomic Digital Clock Auto Set (no back light) - Using radio frequencies broadcast from NIST’s Colorado , the clock will automatically set to the correct time. Automatically adjusts to Daylight ...

With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s used to define the SI second, by the way — [Daniel] looked for ways to sync the ...

The precision of the nuclear clock is predicted to surpass that of atomic clocks in two to three years, and should also be ...

(Courtesy: Chuankun Zhang/JILA) Could a new type of clock potentially be more accurate than today’s best optical atomic clocks? Such a device is now nearing reality, thanks to new work by researchers ...

Frequency measurements using multi-qubit entangled states have been performed by two independent groups in the US. These ...

The clock has been maintained by the Bulletin of the Atomic Scientists since 1947 ... considered various disruptive ...

Small modular nuclear reactors long seemed like moonshots with lots of promise but not enough commercial interest. That ...

"Atomic clocks use quantum mechanics to measure time, while quantum computers use quantum mechanics to perform calculations," Endres says. "Here, we are working at the interface of both." ...

From left to right, Adam Kaufman, Nelson Darkwah Oppong, Alec Cao and Theo Lukin Yelin inspect an atomic optical clock at JILA. Imagine walking into a room where several different grandfather ...

In 2001, Japanese physicist Hidetoshi Katori proposed a new type of atomic clock that only loses a second every 30 billion years, a period longer than the current age of the universe. The ...

But the River Thames is perhaps the choice for the most special deliveries - including an optical atomic clock. A flotilla of 15 boats, led by royal barge Jubilant, has carried the extremely ...
