Actually they've come even further in the field of quantum ... string-field theory? I don't know, but they've found evidence of entanglement. If one particle interacts with another, they sort of bind together as one. One of those two particles can travel to the other side of the galaxy while the other remains in place. No matter the distance between them, they still interact with eachother in realtime. That's a connection that is faster than the speed of light by atleast a thousand times.
Something is connecting these two, if we find out how they do it, we could take advantage of it, and study it even further.

"Quantum entanglement, one of the odder aspects of quantum theory, links the properties of particles even when they are separated by large distances. When a property of one of a pair of entangled particles is measured, the other "immediately" settles down into a state compatible with that measurement. So how fast is "immediately"? According to research by Prof. Juan Yin and colleagues at the University of Science and Technology of China in Shanghai, the lower limit to the speed associated with entanglement dynamics – or "spooky action at a distance" – is at least 10,000 times faster than light."
