Researchers at the University of Ottawa observed that twisted light in a vacuum travels slower than the universal physical constant established as the speed of light by Einstein's theory of relativity. Twisted light, which turns around its axis of travel much like a corkscrew, holds great potential for storing information for quantum computing and communications applications.
