Eric Hudson’s UCLA physics laboratory (Credit: UCLA) Chilling molecules to a fraction of a degree above absolute zero, the temperature at which they can be manipulated to store and transmit data in quantum computers, has proven to be a difficult challenge for scientists. At higher temperatures, molecules rocket around, bouncing into each other and exchanging energy. Any information a scientist attempted to store in such a chaotic system would quickly become gibberish. Now, UCLA physicists have pioneered a new technique that combines two traditional atomic cooling technologies and brings molecules to a frozen standstill by immersing charged barium chloride molecules in an ultracold cloud of calcium atoms.
