Resumo
We analyse how coherence evolves in quantum transmission protocols, such as quantum teleportation and superdense coding, while the message is being transmitted. Then we derive a basic equation that gives the minimum amount of infrastructure needed to create a quantum transmission protocol, with this tool we generalize teleportation and superdense coding for any amount of information and analyze how the coherence behaves when we send large amounts of information.
