- NIST physicists boost 'entanglement' of atom pairs
10-18-2006 · EurekAlert!
Physicists at NIST have taken a significant step toward transforming entanglement -- an atomic-scale phenomenon described by Albert Einstein as "spooky action at a distance" -- into a practical tool. They demonstrated a method for refining entangled atom pairs, a process called purification, so they can be more useful in quantum computers and communications systems, emerging technologies that exploit the unusual rules of quantum physics for pioneering applications such as "unbreakable" data encryption.

- The world's smallest double slit experiment
11-08-2007 · EurekAlert!
Where do the realms of quantum mechanics and classical physics begin to overlap? It's a long-argued question of philosophical interest and practical importance. Now the world's smallest double slit experiment, performed at Lawrence Berkeley National Laboratory's Advanced Light Source and using as "slits" the two proton nuclei of a hydrogen molecule, has shown that quantum particles start behaving in a classical way on a scale as small as a single hydrogen molecule.

- 'Heftier' atoms reduce friction at the nanoscale, study led by Penn researcher reveals
11-01-2007 · EurekAlert!
A research team led by a University of Pennsylvania mechanical engineer has discovered that friction between two sliding bodies can be reduced at the molecular, or nanoscale, level by changing the mass of the atoms at the surface. 'Heavier' atoms vibrate at a lower frequency, reducing energy lost during sliding.
