Entanglement swapping allows for the entanglement of two photons that are separated by significant distances, such as those over n kilometers of optical fibers, without direct interaction. This theoretical framework demonstrates that entanglement is not limited to close proximity, challenging traditional notions of quantum entanglement. The concept is supported by research outlined in the paper available at arXiv: quant-ph/0409093.
