    Entanglement
In summary, entangling distant particles in real life has been successfully demonstrated in various experiments, including the famous Bell test experiments in the 1980s. This involves linking the quantum states of particles separated by large distances through quantum entanglement. Potential applications include quantum communication, cryptography, computing, and studying quantum mechanics. It is possible to entangle particles over long distances, but it cannot be used for faster-than-light communication.

TL;DR Summary
Can you target a distant particle to entangle it?
Is it theoretically possible to target a distant particle and entangle it with a near particle? Or is entanglement only possible with close particles?

Hello

With entanglement swapping, two photons separated by more than n km of optical fibers are entangled, although they never directly interacted : https://arxiv.org/abs/quant-ph/0409093

1. What is entanglement?

Entanglement is a phenomenon in quantum physics where two particles become connected in such a way that the state of one particle is dependent on the state of the other, regardless of the distance between them.

2. How is entanglement achieved?

Entanglement can be achieved through various methods, such as creating a pair of entangled particles through a quantum process or using a quantum channel to entangle particles that are already separated.

3. What is the significance of entanglement?

Entanglement has significant implications for quantum computing and communication. It allows for the creation of quantum networks and secure communication channels that are not possible with classical systems.

4. How does entanglement affect distant particles?

Entanglement allows for the instantaneous transmission of information between entangled particles, regardless of the distance between them. This means that any change in one particle's state will be reflected in the other particle's state, even if they are separated by large distances.

5. Is entanglement a proven phenomenon?

Yes, entanglement has been experimentally verified numerous times and is a well-established phenomenon in quantum physics. It has also been used in practical applications, such as quantum cryptography and teleportation.
