Physicists at Johannes Gutenberg University in Germany are developing something which they call the Mainz interface, and which could eventually lead to a quantum computer -- a whole new way of communicating information. For now, though the Mainz interface is seeking to use laser light traveling through a tapered glass fiber, trapping cesium atoms at the thin center. This center of the fiber is actually thinner than the wavelength of light, meaning that it protrudes into the space surrounding the fiber, "coupling" with the atoms trapped there. Sounds pretty complicated, right? Well, it is, but the researchers are moving along toward the goal of quantum computing. We'll keep you updated on their progress.
