Overview: Entanglement swapping is a fundamental technique in quantum communication and networking that allows the creation of entanglement between distant particles. It enables the establishment of long-distance entanglement, which is crucial for quantum teleportation, quantum key distribution, and the construction of quantum networks.

1. Entanglement Generation: Entanglement swapping begins with the generation of two pairs of entangled particles. These pairs can be photons, atoms, or other quantum systems. Each pair is entangled, meaning the quantum states of the particles are correlated, even when separated by large distances.
2. Bell State Measurement: To perform entanglement swapping, a Bell state measurement is conducted on one particle from each entangled pair. This measurement projects the particles onto a specific entangled state, effectively swapping the entanglement between the two pairs. The result is that the remaining particles, which were not measured, become entangled, even though they have never interacted directly.
3. Applications: Entanglement swapping is a key technique for quantum repeaters, which extend the range of quantum communication by creating entanglement over long distances. It also plays a crucial role in quantum teleportation, where the quantum state of a particle is transferred from one location to another using entanglement. Additionally, entanglement swapping is essential for building scalable quantum networks and enabling secure quantum key distribution.
