What if you had more than one entangled particle (lets say two) and a prearranged yes or no question to be answered, such as “does this star system contain a habitable planet”. If you are at the remote site and your intended message was “no habitable planet” and the first remote particle measured a negative spin you would not use the second particle. Getting a single negative result at the remote site would tell the receiver on Earth (seeing a positive spin on his particle) that the answer was negative.
If the first particle measured ‘positive spin’ at the remote location you would then measure the spin on the second particle at the remote location. Whatever its result the receiver on Earth knowing your first result was positive would see that you had tested the second particle indicating (by a pre-arranged understanding) a reversal of the first result to negative and again know your answer was “no”.
I guess the question is can the receiver on Earth detect if you had measured one or two particle spins states? If the receiver detect any action or result I believe there can be communication with a prearranged system?
