I had to do a bit of research in basic Quantum Computing, when reading about "spooky action at a distance" or entanglement I was intrigued, I though this could be used to transfer information over distances, this seems to be a common misconception, you can read this Forbes article by a Ph.D. astrophysicist to understand why it doesn't work in detail, but I found a helpful analogy. It goes like this.
The Entanglement shoe-box analogy
Assume you have a shoe-box, one of the shoes has been taken and placed at the end of the universe. When you open the shoe-box you observe you have the right shoe, that means the shoe at the other end of the universe is the left one(assuming a normal shoe box). This is how entanglement works. Changing the shoe in the shoe-box in any way has no effect on the shoe that's on the end of the universe, you see the shoe you get the information and that is it. In the article it's said that forcing a state (changing the shoe) would break the entanglement. It is also stated on entanglement that "You know something important about the sum of both states together", or in the shoe-box you know that it should contain both a left and right shoe(normally). :)
