I am not a scientist, so that's why I've come here...to hopefully find out if this would be possible.

Ok, so I started learning about quantum entanglement and I stumbled upon an idea for instant data transmission through space.

The idea is fairly basic, because quantum entangled particles are dependent on each other to create 1 shared state...(I think) we could separate two entangled particles and then modify one to create an instant change on the other particle.

This change would be read and computed as binary code 1-0-0-1-1-0-1-0 for example.

Here's the best way i can explain my theory,

example

Simply put as one question, is instant data transmission possible in this way? Or at least faster than light (laser arrays)?

No, you cannot use this for faster than light communication. The two typical ways that people think this could work are:

  • Alice measures her qubit in a fixed basis, creating an instantaneous change in Bob's qubit. This is true, but the measurement outcome is random. Alice has no control over what measurement outcome she gets, so no information is transmitted in that protocol.

  • Alice chooses a measurement basis, and that choice is the bit she tries to communicate. Bob's qubit is instantaneously updated, but he has no way do determine what basis she used.

Either way, there's no way around it.
