University of Tokyo pair invent loop-based quantum computing technique

Japanese scientists have invented an approach to quantum computing that renders a far larger number of calculations more efficiently than existing quantum computers. Under the new method, many pulses of light, each carrying information, are allowed to go around in a loop circuit indefinitely. The circuit performs multiple tasks, switching from one task to another rapidly through instant manipulations of the pulses.
