"Physicists one step closer to creating real-life lightsabers"

A team of MIT and Harvard physicists accidentally found lightsaber like properties when attempting to develop photons to be used in a quantum supercomputer. No lightsaber has been produced but it is the beginning steps to understanding how to make one. The creation of a real life lightsaber would be just in time for the new Star Wars movies coming out.

"Most of the properties of light we know about originate from the fact that photons are massless and do not interact," Lukin said. "What we have done is create a special type of medium in which photons interact with each other so strongly that they act as though they have mass, and bind together to form molecules."
