The problem is with the usage of the word "communicate". Normally communication would mean "transmit information". Quantum entanglement does not allow this.

The problem is with the usage of the word "communicate". Normally communication would mean "transmit information". Quantum entanglement does not allow this. With entangled particles a measurement on one instantly changes the statistical behavior of the other. However there's no way to see this effect until you compare the statistics between the two particles (which probably requires an ensemble of particle pairs to be measured, not just one), so you can't actually use the effect to transmit information.
I don't think there's a good English word for the concept of an influence that isn't causal and doesn't transmit information. That's why it's often called "spooky action at a distance" and why attempts to describe it with simple English sentences are likely to lead to confusion.
