(Essentially, if you split a photon so one goes left at the speed of light and the other goes right at the speed of light and then you measure the one on the left...the one on the right somehow 'knows' what you did to the one going left.)

Quantum entanglement shows that state between entangled particles can be transferred instantly regardless of distance, but you still can't violate causality that way; you can't use that to communicate information faster than light.
If you want to communicate using quantum entanglement to get the original information you still have to have some information that is transferred via a traditional method that's bound by the speed of light.
