By using paired, offset optical combs and RF electronics, researchers devised a unique atomic-clock architecture.

Moreover, ISRO has been working on high precision atomic clocks based on rubidium. Such factors are ... and technologies such as 5G networks and GPS alternatives will need accurate timekeeping ...

One example of this type of sensor is an atomic clock, which goes inside electronic devices to provide the same sort of precision referencing as wireless GPS. They could eliminate the need for the ...

Rubidium atoms in the atomic beam provide the microwave quantum transition that is used by the clock to provide a relative frequency ... and underwater exploration where GPS signals do not reach by ...

This technology, called the 'microcomb chip,' could make optical atomic clocks, the most precise timekeepers in the world, compact enough for everyday use. Credit: Kaiyi Wu This breakthrough could ...

Every single day, humans rely on hundreds of hidden clocks. GPS location, Internet stability, stock trading, power grid management ... all rely on atomic clocks in order to work. Many of those ...

An atomic clock ... scale optical clock was also proposed and demonstrated with better frequency stability and accuracy, which is mainly based on two-photon transition of Rubidium atom ensemble.

The plan is simple: to develop a more secure alternative to GPS by enabling the portable use of new atomic clocks, rather than relying on signals from satellites in space that can be jammed.
