Here is the original paper on Arxiv: http://arxiv.org/abs/1505.03859 http://arxiv.org/abs/1505.03859 What the linked article fails to mention among all the fantasizing about light sabers is that this kind of interaction is only possible in matter. These "molecules made of light" can only exist when photons interact with atoms while the light travels in a very special medium. In vacuum, photon-photon interactions do not allow for any kind of bound states like that.

Just to echo your point: This is an interesting proposal more because of the ability to use for photonic information applications (quantum gates and such) then for light-sabers. Fair warning to those looking at the original paper: I have my PhD as an experimentalist in this field, and it took me a while to work through what they were proposing :)
