To me the quantum entanglement theory has stumbled on a new discovery of interaction over vast distances. I don't think there is any faster than light particle travel, there is just a literal entanglement and relationship on a sub atomic level. We are at the beginning of a new understanding of the nature of matter, time and space. There can only be a reference if there are two coordinates. This will grow into yet a new understanding of matter, time and space. It will be an even bigger learning curve than Einstein's Relativity. In fact, he spotted relativity and is the forerunner of that which perplexed him. Entanglement is a kind of relating. Early days yet. It is obviously a lot more complex than just behaviour of frequencies and waves.
Frame of reference:
"In physics, a frame of reference (or reference frame) consists of an abstract coordinate system and the set of physical reference points that uniquely fix (locate and orient) the coordinate system and standardize measurements."
No coordinates, no reference. In terms of physics we are still in kindergarten. Lol, especially me, my brain is beginning to hurt already!
The way people get around the idea that entanglement implies instantaneous communication is that no actual information is passed when the entangled particles affect each other. The argument is as follows (using a non-QM example):
Say you agree to send out two beams of light to your two friends who live on opposite sides of the galaxy (you live in the middle). Ahead of time you tell them that if one of the beams of light is red the other will be blue. So you send the blue beam to your friend on one side and immediately she knows that your other friend is receiving a red beam at the same time. Aha! You say, my friends have now communicated at a speed faster than the speed of light and violated relativity, but no real information has been passed between them. You have told both of them at a normal sub-luminal speed about what you just did and that's all. (A way of proving there's no faster than light communication is that you could lie and send them both the same coloured beam of light and they would never know!).
With QM is gets a bit more complicated because theoretically no-one knows the state of the particle until it has been observed, but you still cannot affect the state of the particle so the argument is the same.
There is a nice article about this stuff here which talks about the EPR (Einstein-Podolsky-Rosen) paradox. Einstein and his colleagues were very uncomfortable when they heard about quantum entanglement and devised the EPR paradox to 'prove' that it couldn't be true (meaning that while you hadn't observed the particle yet it still has a state). It was proved in one line of algebra that this idea of "hidden" variables couldn't be true.
As I said above though, quantum entanglement still does not imply faster than light communication. You cannot affect which state the particle goes into, even though it doesn't 'decide' on its state until you observe it.
I don't think there is any faster than light particle travel.
