Hey all. I know it's been a long time since I have posted, but I just finished reading Entanglement: The Greatest Mystery in Physics, by Amir D. Aczel and I had a question concerning the conclusion of the work.
He made the claim that GR was not violated by entanglement since messages could not be transmitted due to the impossibility of predicting the spin of an entangled particle before measurement, and that after spin was detected you had to transmit the message of it's state via a conventional channel.
My question was if instantaneous communication could be achieved by using time-shifted measurement of states.
Let's say that Bill is on the Earth and Alice is traveling to Mars in a manned space capsule. Before launch sophisticated as-yet unrealized equipment to quickly measure the spin of entangled particles was installed with a few hundred or thousand entangled particles mated between matching equipment at Houston and in the spacecraft . Before launch, Bill measured the states of his particles, communicated the states to Alice, and Alice mesured her states and verified pairs of opposites. The equipment then continuously monitors the states of the pairs in both Bill and Alice's equpment. After Alice leaves Earth, bill needs to send her a message and does so by altering the states of his particles in a predertimined ordered fassion. Wouldn't Alice's mated pairs also alter states in a predictable fassion, or would the possible states to which they are altered not be deterministic? Obviously if this is possible QE could be used to transmit messages at infinite speed, eliminating the need for time delay in communications, interferrance, etc...
