Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a separate line of theoretical work suggesting that time crystals, exotic quantum ...

An electronic system requires a reliable, precision timing reference: the system clock. We examine and compare two forms of system clocks, the Crystal Oscillator and the Phase Locked Loop Synthesizer ...

ON Semiconductor today announced the further extension of its silicon based crystal oscillator (XO) clock module range. The six new additions to the NBX series provide a cost-effective, high accuracy ...

This past August, scientists at the National Institute of Standards and Technology (NIST) unveiled a development that could deliver a thousand-fold performance improvement over the quartz crystal ...

The next generation of atomic clocks “ticks” at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...
