I happened to take out two library books on quantum mechanics today, so hopefully I will be able to give a good answer before they have to be returned!
I don't see how this is transmitting any data. For data to be transmitted, we would need to know the state of one of the particles, and as far as I know once a particle's state has been measured the two are no longer entangled. If it were the case that we could change the polarization, for example, of a particle and witness its partner 500km away flip polarity instantaneously then we would already be capable of faster than light communication.
It strikes me as odd that the diagram shows both photons being emitted from the same source. They would have to be emitted at some time of course, but for data to be transmitted between them the focus should be on containing the photons at their destination and manipulating them to transmit data instantly.
This seems like a big misunderstanding of what the experiment is about. I can't help questioning the scientific pedigree of the writers when two of the six "You might also like" links are about sexy celebrity Halloween costumes.
