The European Space Agency has launched two atomic clocks on a SpaceX rocket to the ISS to test Einstein's theory of ...

Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by using the quantum behavior of atoms to measure time. Discover how these incredibly precise clocks ...

The results of this research were published in Nature Photonics. Traditional atomic clocks, although precise, use microwaves to measure time. Optical atomic clocks, on the other hand, use laser light ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block ...

Atomic clocks keep getting smaller, lower power, and better—Microchip’s latest chip-scale version leverages EXMO technology to bring its height down to half an inch. Where and why tiny ...

Symmetricom has squeezed an atomic clock into 17cm3. Called the SA ... Alongside the 10MHz output is a 1Hz output, and time of day is available over the oscillator’s RS-232 interface. The interface ...

The European Space Agency (ESA) is getting ready for the launch of an atomic clock system that aims to validate elements of Einstein’s theory of general relativity but could have implications ...
