Only if you want to communicate a random bit-string. (Which is very useful as a key-agreement protocol for encrypting communication over more normal channels, which alas are limited to light-speed.)

Let's say you could change the direction of spin of an atom's electron. According to the article, the 'mate' atom's electron would spin in the opposite direction, automatically.

[In a pair of entangled particles, if one particle is observed to have a specific spin, for example, the other particle observed at the same time will have the opposite spin. ]

That is a definite form of communication, 1/0. All you would have to do is 'modulate' the spin of one particle, then detect that opposite spin in the other particle. That opens up whole new possibilities in encrypted communications that is not possible to break........
