COLUMBUS, Ohio - Scientists at Ohio State University have taken a step
toward the development of powerful new computers -- by making tiny holes
that contain nothing at all.
The holes -- dark spots in an egg carton-shaped surface of laser light --
could one day cradle atoms for quantum computing
Worldwide, scientists are racing to develop computers that exploit the
quantum mechanical properties of atoms, explained Greg Lafyatis
associate professor of physics at Ohio State
<http://www.physics.ohio-state.edu/> . These so-called quantum computers
could enable much faster computing than is possible today. One strategy for
making quantum computers involves packaging individual atoms on a chip so
that laser beams can read quantum data.
Lafyatis and doctoral student Katharina Christandl
recently designed a chip with a top surface of laser light that functions
as an array of tiny traps, each of which could potentially hold a single
atom. The design could enable quantum data to be read the same way CDs are
