Scientists use quantum device to slow chemical process by factor of 100B
In a world-first experimental result, scientists at the University of Sydney have used a quantum computer to coax an atom to behave the same way as a photo-chemical process that underpins the speed of human vision and solar energy harvesting - only at speeds 100 billion times slower than in nature.
