Researchers from The Australian National University (ANU) have developed a method of freezing and storing light, an important step on the road to developing quantum computers. Most switches used in quantum computing experiments are made up of trapped ions or semiconductor particles, suspended in a state of quantum superposition. Photons, however, could interface much more efficiently with fiber optic networks, without the need for a way to translate the information between the qubit -- the quantum-computing equivalent of a classical computer bit -- and the computer's network or interface.
