In the pipeline: manipulating atoms.(rubidium atoms guided through an optical pipeline by laser of precise wavelength)(Brief Article)

From: The Economist (US) | Date: October 28, 1995 | Copyright information

AMONG optimistic technologists, the idea of building machines and circuits atom by atom is popular. Scientists have shown that they can arrange atoms individually, and designers are starting to speculate about manufacturing on this minuscule scale. Now physicists from the University of Colorado at Boulder have built what might become the plumbing to carry atomic raw material from stockroom to factory.

The raw materials which Dana Anderson, Eric Cornell and their colleagues deliver are rubidium atoms. Their pipeline is a hollow optical fibre with a laser shining down it. The laser, ...
