I prefer hope and dreams that if you get a little foot in the door of physics you may bust it open some day. No argument from me that there is a long way to go and propably regulariy in the wrong direction. I am however also sure that we have enough glimpses seen that einstein is not the last of it.

I do understand this a bit different and would expect that this would be actually possible. According to the relativity theory the point is that the "spooky entaglement" happens at identical times everywhere.

Maybe this paper is better:

or this

"teleportation" is in my understanding "timeless" as it happens between entagled entities.

My understanding of


In the second part of the paper, Schrödinger showed that an experimenter, by a suitable choice of operations carried out on one member of an entangled pair, possibly using additional ‘ancilla’ or helper particles, can ‘steer’ the second system into a chosen mixture of quantum states, with a probability distribution that depends on the entangled state.

Is that actually you can change one system by changing the other.

I am pretty sure that i read an article that with bose-einstein Kondensator you can actually transmit information between them. The whole point is the measurement on the other sire becoming identical. With photons entangled pairs you will need some back channel however with larger entangled quantum entities I believe it was shown to actually be able to transmit the information Thus was shown by schrödinger for example https://plato.stanford.edu/entries/qt-entangle/

Entangled particles can transport information instantly and can well be used for transmission of information, used eg in quantum cyrptography. It will probably depend on the definition of "faster of tje speed of light" as you would have to separate two entangled particles (or more btw) and transport one portion with the (current known) restriction of the relativity theory to another place - probably far below the speed of light. I'd believe that the use of entangled particles would probably be rather a "secret" communication tool as it probably will not become cheap and has some restrictions like limited amount of information. However it does not need any direct line of communication.
