What role does entanglement play in the process of quantum teleportation, and what are the main steps involved in achieving teleportation?

In quantum teleportation, entanglement is used to transfer the state of a particle from one location to another without physically moving the particle itself. The main steps involve: (1) creating an entangled pair of particles, (2) performing a Bell-state measurement on one of the entangled particles and the particle to be teleported, (3) sending the measurement results to the receiving location, and (4) using the results to apply an appropriate operation on the second entangled particle to reconstruct the original state.
