As I understand it * ....
... you can't use entanglement to send information between two places instantaneously (in the sense of sending a bit stream representing the letter 'A', for example), but you can use it to send information between two places (at the speed of photons) in such a way that nobody can intercept or listen in to the data transfer without the end parties being aware that this is happening. Hence its potential for use in very secure data networks.
