I'm having a hard time understanding why it is not possible to communicate faster than light with entangled qubits. Now, this is my hypothesis.
A and B have a pair of qubits, and 2 synced clocks at 12:00. Now A and B agree that every 5 minutes, B will observe his qubit (at 12:05 ; 12:10 ; ....), to see whether it is in state 1 or 0. A will prepare an X gate and a CNOT gate and let's say A's qubit is the control qubit and B's qubit is the target qubit. B will also know which gates A is using to manipulate the control qubit. And so, B goes somewhere very very far away with one of the synced clocks. Now, both qubits are in the initial state (00), if A wants to send to B the state 0, A does not have to do anything. And if A wants to send to B state 1, A will apply the X gate to his qubit, resulting (10), and put those through a CNOT gate, which will result in the state (11), so B with his target qubit will see (1).
Recall that we have 2 synced clocks, at 12:00 and B will measure his qubit every 5 minutes. The reason for the synced clock is for B to know when to measure his qubit, so his measurement does not occur before A, which will mess up the whole communication purpose. And for A, having a 5-minute rest time between each measurement can help him reset the control qubit to state (0) and decide whether to use the X gate or just put the qubit through the CNOT gate. (So by using the X gate and CNOT, A will control what B receives).
As I said, I'm having a hard time understanding the topic so there might be a fundamental mistake so please tell me.
