Quantum entangled particles can't influence each other; they just allow you to infer information about one particle by observing the other. It's like if you randomly put a red and a blue ball in two different boxes without looking, then moved them far apart. Opening one box and seeing a red ball instantly tells you the other box has a blue ball, no matter the distance, but no information has been transmitted faster than the speed of light (because the boxes can only move slower than light).
