- 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.

- Researchers design copper connections for high-speed computing
02-11-2008 · EurekAlert!
As computers become more complex, the demand increases for more connections between computer chips and external circuitry and better connections that operate at higher frequencies with less loss. Georgia Tech researchers are developing new methods to improve these two types of connections to increase the amount and speed of information that can be sent throughout a computer.

- Physicists pin down spin of surface atoms
09-12-2007 · EurekAlert!
UC-Berkeley physicists have successfully measured the atomic spin of an isolated atom, one of the necessary steps on the road to quantum computers and spintronics devices. Using a scanning tunneling microscope with a spin-polarized tip, Michael Crommie and colleagues mapped the surface topography and the surface energy levels to determine the spin of adatoms, the first time this has been measured directly.

- UCLA scientists working to create smaller, faster integrated circuits
12-19-2007 · EurekAlert!
Integrated circuits are the "brain" in computers, cell phones, and many other electronic devices. A team of UCLA scientists has demonstrated substantial improvements in integrated circuits, also known as silicon chips, achieved not by costly improvements in manufacturing, but by improved computer-aided design software based on better mathematical algorithms.

- Physicists reveal water's secrets in journal 'Science'
03-02-2007 · EurekAlert!
Equipped with high-speed computers and the laws of physics, scientists from the University of Delaware and Radboud University in the Netherlands have developed a new method to "flush out" the hidden properties of water. The research is reported in Science. Their first-principle simulation of water molecules -- based exclusively on quantum physics laws -- has numerous applications, from biological investigations of protein folding and other life processes, to the design of the next generation of power plants.

- With computers, astronomers show predicted present day distribution of elusive first stars
12-11-2006 · EurekAlert!
With the help of enormous computer simulations, astronomers have now shown that the first generation of stars -- which have never been observed by scientists -- should be distributed evenly throughout our galaxy, deepening the long-standing mystery about these missing stellar ancestors. The results are published in this week's issue of the Astrophysical Journal.

- Expressive robot computers
03-21-2007 · EurekAlert!
Imagine if your computer could tune into the mood you're in, tilting its screen to one side when you look gloomy or swing cheerfully upwards when you perk up. RoCo is the world's first expressive computer developed by MIT in the US, which can detect when the user moves and adjust its posture accordingly.
