I'm still learning Quantum Information right now, especially with Quantum Teleportation (QT). I have found an interesting article suggesting a Simplified Protocol of QT that doesn't need classical channel. Here's the link for the article :

This protocol is more satisfying and make sense for me. However, it makes me wonder, why classical channel should be used in the first place, if this protocol is more simple and efficient?
