This repository is a work in progress database of research on Wigner's Friend and Local Friendliness. There are many missing! Please do add suggestions.
Please open a pull request if you'd like to add a new paper. We prefer open access links.
Some experimental papers also have theoretical results. In reverse chronological order.
