The goal of this blogpost is to explain quantum capacity theorem and its proofs (achievability and converse). First, we shall build our intuition through a toy example of private classical communication and creation of one distance-separated shared entanglement using a specific noisy quantum channel. Finally, we shall dive into the statement and proofs of quantum capacity theorem.
