Solid Light for Tomorrow's Computers?

(Credit: Image courtesy of University of Melbourne) Quantum control: A potential design for a device which controls light. The block with the holes in it is a piece of diamond. The red spots are the particles of light 'stuck' in place, rather than roaming around freely.
A totally different way of thinking about light, but possibly a way to make quantum computers.
“Solid light photons repel each other as electrons do. This means we can control photons, opening the door to new kinds of faster computers,” says Dr Greentree. “Many real-world problems in quantum physics are too hard to solve with today’s computers. Our discovery shows how to replicate these hard problems in a system we can control and measure.”
