The speed limit of C is not an explicit requirement of quantum mechanics as I understand it, but it is a requirement that appears to be obeyed in experiment.

But in order to use quantum entanglement to pass information there has to be a real particle that travels the distance. Whatever limits the speed of that particle also limits the speed of the information transferred by quantum entanglement. That limit would be set by relativity.

My limited understanding of entanglement is that you wind up with a Schrodinger's Cat situation until you transmit end-state information in real time back to the observer, which obviously removes the advantage of entanglement-enabled communications.
Causal picturesThe notion of going back in time is acausal, meaning it is excluded automatically in a Hamiltonian formulation. For this reason, it took a long time for this approach to be appreciated and accepted. Stueckelberg proposed this interpretation of antiparticles in the late 1930s, but Feynman's presentation made it stick.In Feynman diagrams, the future is not determined from the past by stepping forward timestep by timestep, it is determined by tracing particle paths proper-time by proper-time. The diagram formalism therefore is philosophically very different from the Hamiltonian field theory formalism, so much so Feynman was somewhat disappointed that they were equivalent.They are not as easily equivalent when you go to string theory, because string theory is an S-matrix theory formulated entirely in Feynman language, not in Hamiltonian language. The Hamiltonian formulation of strings requires a special slicing of space time, and even then, it is less clear and elegant than the Feynman formulation, which is just as acausal and strange. The strings backtrack in time just like particles do, since they reproduce point particles at infinite tension.If you philosophically dislike acausal formalisms, you can say (in field theory) that the Hamiltonian formalism is fundamental, and that you believe in crossing and CPT, and then you don't have to talk about going back in time. Since crossing and CPT are the precise manifestations of the statement that antimatter is matter going back in time, you really aren't saying anything different, except philosophically. But the philosophy motivates crossing and CPT.
Had a moment of confusion. It isn't anti-matter in its real state I think that provides reverse time communication but rather anti-matter in the vacuum state. The annihilated form of it. I think it may provide the reverse time communication to collapse states. I think its that reverse time that provides the bridge that links quantum states. For instance light as a wave passes through two slits. The wave pattern predicts the appearance of the photon but once the photon appears all the energy of the photon is concentrated at the point of absorption. Its almost like the reverse time operator goes back in time and focuses the energy at that exact location. Creating electron-positron pairs in the vacuum in a quantum states of superposition. Its like they were created out of the vacuum but the vacuum has not determined their exact orientation yet, upon interaction the vacuum uses the anti-matter in the vacuum state or the virtual stuff, to determine the final state of the other quantum entangled particle. The wormhole bridge between the two. Tunneling for instance. A particle bangs on a barrier and it has a vacuum wave associated with the particle so particle-wave hybrid. Compound that the vacuum has inherent vacuum energy fluctuations if the particle's vacuum waves passes through the barrier then based on the quantum vacuum energy fluctuation there is a chance the far part of the wave will receive enough energy to re-create the particle on the other side of the barrier. When the particle is created on the other side of the barrier it induces reverse time operators that annihilate the particles previous position via negative energy and the particle exists at its new position. I suspect that the nature of Quantum reality is fundamentally related to the vacuum and negative energy, reverse time operators. Even Richard Feynman diagrams I have been told have reverse time operations.

As it falls in it encounters vacuum polarized electron positron pairs via the atoms electric field. As it falls in it emits energy and it trapped around the atom in a wave state. I think it exist mostly as a vacuum fluctuation. The electron looks like a cloud because it is a cloud of vacuum fluctuation. It isn't actually whizzing around the nucleus, but the vacuum wave is, so hence no radiation. Even radioactive decay.

General relativity might be speculated to be something similar, where matter polarizes the vacuum where negative energy reduces the local mass distributing it over space - a field. the build up of negative energy near matter, causing lower altitude clocks to tick slower than those higher. Possibly related to the nucleus of atoms polarizing the vacuum.

Just forming sentences out of terms from physics in a different order than others isn't new physics.
Let us speculate. Say we have two non antimatter ions Quantum entangled and then separated over a large distance. If anti-matter was the reverse time operator there would be no anti-matter. however, there is anti-matter in the vacuum and that antimatter is never truly annihilated because it can never reach an absolute zero temperature. So when one state collapses the other state instantly collapses.It is the same with photons through the double slit experiment. The photon wave passes through both slit and touches all points on the screen. Even though the wave touches some points on the screen first rather than other points later. At some point the vacuum wave associated with the photon and vacuum thermal fluctuations finds just the right frequency to be absorbed. When it is absorbed the signal can propagate back in time and instantly cancel the wave. The energy is then concentrated at that exact point as a photon.Also with quantum tunneling negative energy swallows the previous particles position. If I remember correctly Quantum tunneling appears to be instantaneous.

There are multiple problems, but one repeated problem is your use of the word "instantly/intantaneous." That word is literally undefined when talking about relativity (It can be defined, but not in an absolute sense like you are using it.) Also, other than containing the word "anti-matter" there seems to be no connection between any of the sentences in your first paragraph.

It was spooky because it was faster than light or instantaneous.
