The way quantum entanglement can be described is like a pair of socks. If I give you one of my socks and then travel to the other side of the universe, you have no idea which sock you have.
But then if I put my sock on my right foot, your sock instantly becomes the left sock, faster than the speed of light would allow you to see my feet.
Of course what you can do with that knowledge is where the research is being done. At present we're only just learning to walk, bare foot.
