"To create the long-sought light matter, the team shot two photons into a cloud of rubidium atoms just a few degrees above absolute zero."

"While lightsabers may be a long time off, this kind of light manipulation should make quantum computers more efficient and could even lead to the creation of all-light 3-D structures. (So, fans of Star Trek and its holodeck can join in the fun, too.)"

Oh sure, if you can survive temperatures at a few degrees above 0 k.
