Quantum computer may be brought out by the study of atoms dancing in laser light.

Suspended in laser light, thousands of atoms pair up and dance, each moving in perfect counterpoint to its partner.They are the building blocks of what may one day become an enormously powerful quantum computer capable of solving in seconds problems that take today's fastest machines years to crack, U.S. physicists said Wednesday (July 25).

"You can do the equivalent of multiple classical calculations at the same time in the quantum world," said Trey Porto, a researcher with the U.S. Commerce Department's National Institute of Standards and Technology or NIST, whose work appears in the journal Nature.

Porto and colleagues have coaxed pairs of super-cold rubidium atoms to repeatedly swap positions, a feat that could make them useful for storing and processing data in quantum computers.
