This is one of the gems of the Big Bang theory, every atom is entangled, but their changes of state are communicated at c, otherwise cause and effect (C&E) would be simultaneous.
C&E and instantaneous events exist at the subatomic level of the atom, but cease beyond that range. Outside the subatomic and atomic level a classical communication channel is required.
For fun, lets say you are piloting a photon starship that uses antimatter for its propulsive power. It's too hard to manufacture on board, but you can take a small quantity with you. At 5000 light years out you run out of gas. So now you are waiting for the gravitational beam in the Aristarchus crater antimatter facility on the Moon to send information that will change the state of your remaining entangled matter into antimatter. Relative to Earth you had better be zipping a tiny fraction below light speed, because it will still take 5000 light years as seen by an observer on Earth to reach your ship. But to you a few days wait is nothing.
Oh yeah, and your QT account had better have good credit, hopefully you put a dollar in it before leaving so the interest can cover the charges for manufacture and transmission.
