Harvard, MIT scientists create real lightsaber

Scientists have figured out how to bring the lightsaber from a galaxy far, far away to one much closer.

Researchers at Harvard and the Massachusetts Institute of Technology have discovered a new state of matter that they say looks a lot like the lightsabers used in "Star Wars."

MIT professor of physics Vladan Vuleti and Harvard professor of physics Mikhail Lukin led the study.

Unlike typical lasers, they used what they call "photonic molecules." Rather than pass through each other, photons bind together, creating said molecules.

The scientists said they think the interactions between photons will probably not be useful as Jedi weapons, but they will aid quantum computing in the future.
