MIT Research Shows New Magnetic State That Could Aid Quantum Computing

Look, the Ansible is not possible with quantum entanglement. Also, the original science fiction concept of the Ansible did not involve quantum entanglement. A fictional Ansible is built from a fictional particle that exists simultaneously in two locations and never decays. For an Ansible to work, there must be a special frame of reference in Relativity, but General Relativity does not allow for treating any frame differently from any other frame.

Entanglement is the splitting of a bit of quantum information across two interactions. Neither of the two interactions can possibly have any effect on the other; all that happens is that the entangled measurements from both interactions sum to zero. Every interaction between particles either creates entanglement or destroys it or performs some combination of the two.

Consider that they must sum to zero in every frame of reference under General Relativity: no interaction can determine the results of another because then there would exist some frame of reference where the effect would precede the cause.

That's the bonkers thing about entanglement: it implies determinism but also sidesteps it at the same time.
