ENTANGLED PHOTONS COULD PROMISE LIGHTNING-SPEED COMPUTERS

     Defying traditional laws of physics, researchers may have 
found a way to blast through imminent roadblocks on the highway to 
faster and smaller computers.

Using modern quantum physics, a research team from NASA's Jet 
Propulsion Laboratory (JPL), Pasadena, CA, and the University of 
Wales in the United Kingdom has discovered that entangled pairs of 
light particles, called photons, can act as a single unit, but 
perform with twice the efficiency. 

Using a process called "entanglement," the research team proposes 
that existing sources of laser light could be used to produce 
smaller and faster computer chips than current technology allows. 
Their paper appears in the today's issue of the journal Physical 
Review Letters.
