According to this report by IT Pro, scientists have managed to construct a lattice of rubidium atom pairs that swap spins states. This swapping creates a logical operations such as an if/then statement. If two atoms or quantum bits have opposing states then they should exchange values. The scientists reckon this type of computing could solve problems in hours that today's supercomputers would take years to crack.
