Entanglement and two electrons separated by the universe

In summary, splitting one member of an entangled pair does not cause the other member to split, it only results in a change to the entangled system. This is similar to splitting entangled spin 0 pions.

If 2 electrons were created at the same time and entangled. And you sent A to the other side of the universe and then you somehow split B. Since the electron being split is connected to the A electron and mimics the electron being split... Would that create matter and would the A electron split?
That is if we could split electrons and is not an elementary particle.

A very good question, I think. It's better to think about two entangled spin 0 pions which spontaneously decay. As you said, the electrons do not decay.

No, splitting one member of an entangled pair (using something like spontaneous parametric down conversion for photons) does not cause the other member of the pair to spontaneously split, it just changes a two-particle entangled system to a three-particle entangled system.
 

1. What is entanglement?

Entanglement is a phenomenon in quantum mechanics where two or more particles become connected in such a way that the state of one particle depends on the state of the other, even when they are separated by large distances.

2. How do two electrons become entangled?

Two electrons can become entangled through a process called quantum entanglement, where they are created or interact in such a way that their states become correlated. This means that the state of one electron cannot be described without also describing the state of the other.

3. Can entangled electrons communicate with each other?

No, entangled electrons cannot communicate with each other. Although their states are linked, they cannot be used to send information or messages. This is because any attempt to measure or observe one of the electrons will cause the entanglement to break, and the states of the particles will become uncorrelated.

4. What is the significance of entanglement and two electrons separated by the universe?

The significance of entanglement and two electrons separated by the universe lies in the fact that it challenges our understanding of traditional physics and opens up possibilities for quantum communication and computing. It also suggests that there may be some underlying connection between particles that we have yet to fully understand.

5. Can entanglement be used for faster-than-light communication?

No, entanglement cannot be used for faster-than-light communication. While the state of one particle may be determined by the state of the other, there is no way to control or manipulate this relationship, and therefore it cannot be used to send information faster than the speed of light.
