In a recent tweet I asked colleagues in quantum information theory about papers they consider must-reads in our field. There were many responses leading to a great list of papers that I want to collect here. They are listed below, sorted by year of appearance on the arXiv. This list does not claim to be a complete or definite list of important quantum information theory papers. It's merely a list of papers that came to the mind of quantum information theorists active on Twitter.
