NIST atom interferometry displays new quantum tricks
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a novel way of making atoms interfere with each other, recreating a famous experiment originally done with light while also making the atoms do things that light just won't do. view more (2007-05-29)
Long-distance record -- 'Quantum keys' sent 200 kilometers
Particles of light serving as "quantum keys"-the latest in encryption technology-have been sent over a record-setting 200-kilometer fiber-optic link by researchers from the National Institute of Standards and Technology (NIST), NTT Corp. in Japan, and Stanford University. view more (2007-06-04)
Tandem ions may lead the way to better atomic clocks
Physicists at the Commerce Department's National Institute of Standards and Technology (NIST) have used the natural oscillations of two different types of charged atoms, or ions, confined together in a single trap, to produce the "ticks" that may power a future atomic clock. view more (2005-07-29)
Scientists identify brain circuits used in sensation of touch
The ability to tactually recognize fine spatial details, such as the raised dots used in braille, is especially important to those who are blind. view more (2007-10-11)
