Ugh, typical poor science journalism strikes again. Quantum entanglement can absolutely not be used to transfer information. Two problems are you can't travel faster than light, information included, and second is measuring the spin of an entangled particle only works if you know the state of the other one. So no, you cannot transmit encyclopedias of data using quantum entanglement. As for the rest of the story, it sounds like entanglement can work across time. Flipping the state in the past instantly flips it in the future. However, in either direction of time the observer already knows the state so no info transfer, no causality breakage.
