Physicists have demonstrated all the ingredients of a nuclear clock — a device that keeps time by measuring tiny energy shifts inside an atomic nucleus. Such clocks could lead to vast improvements in ...

Scientists in Germany have unveiled that the world’s most precise mobile atomic clock is so accurate that it will be off by ...

Adtran has released two optical cesium atomic clocks, the OSA 3300 Super High-Performance (OSA 3300 SHP) and the OSA 3350 Super Enhanced Primary Reference Clock+ (OSA 3350 SePRC+). The devices use ...

New Oscilloquartz models bring advanced optical pumping technology to telecom, defense, data center and metrology networks Adtran’s unique cesium clock solutions deliver longer service life and ...

FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every six weeks, an atomic clock might not lose a thousandth of one in a decade.

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...
