The device, which works at microwave frequencies, may soon be extended to trap visible light, leading to an entirely new way of harvesting solar energy to generate electricity. (newscientist.com)
This sets the clock ticking rate at a specific microwave frequency. (sciencedaily.com)
The logic clock is based on a single aluminum ion (electrically charged atom) trapped by electric fields and vibrating at ultraviolet light frequencies, which are 100,000 times higher than microwave frequencies used in NIST - F1 and other similar time standards around the world. (nist.gov)
