Strontium atomic clock demonstrates super-fine 'ticks'

Strontium atomic clock demonstrates super-fine 'ticks' from PhysOrg.com

Using an ultra-stable laser to manipulate strontium atoms trapped in a "lattice" made of light, scientists at JILA have demonstrated the capability to produce the most precise "ticks" ever recorded in an optical atomic clock—techniques that may be useful in time keeping, precision measurements of high frequencies, and quantum computers using neutral atoms as bits of information.
