Entanglement and event horizon

In summary, the conversation discusses the possibility of entanglement still existing between two particles that have passed the event horizon of a black hole. However, it is noted that information cannot be sent through entanglement alone and a classical channel is needed. The conversation also includes a request for a recommendation for a book on quantum physics and entanglement, with the responder providing a link to a relevant book.

If one of two entangled particles passes the event horizon of a black hole, will the entanglement still exist? Because that would mean information can come from a black hole.

You can't send information via entanglement only, you need a classical channel in order to relay information. So even if the entanglement persists, there's no way to relay information from inside the black hole.

Mmm...

Can you recommend me a good book about quantum physics and maybe entanglement in particular?
I'm a M.D., who may have a good brain, but my physics is high school level.

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 is dependent on the state of the other, even if they are separated by large distances.

2. How does entanglement work?

Entanglement occurs when two particles interact with each other and then become separated. This interaction causes the particles to become "entangled" and share a quantum state. This means that any changes to one particle will affect the other, no matter how far apart they are.

3. What is an event horizon?

An event horizon is a boundary in space around a black hole where the gravitational pull is so strong that nothing, including light, can escape. It is the point of no return for anything that gets too close to a black hole.

4. How are entanglement and event horizon related?

There is a theory that suggests that particles that fall into a black hole become entangled with the particles inside the event horizon. This means that any changes to one particle inside the black hole will affect the other particle outside the black hole, even though they are separated by the event horizon.

5. What is the significance of entanglement and event horizon?

The relationship between entanglement and event horizon is still a topic of research and debate in the scientific community. It has the potential to shed light on the mysteries of black holes and the behavior of particles in extreme conditions. Understanding this relationship could also have implications for quantum computing and communication technologies.
