Right now, there’s been a resurgence of interest in ideas of applying quantum mechanics and quantum information to ideas of quantum gravity, and what the fundamental theory of the universe actually is. It turns out that quantum information has a lot to offer people who are looking at problems like, for instance, what happens when you fall into a black hole? (By the way, my advice is don’t do that if you can help it.) If you fall into a black hole, does any information about you ever escape from the black hole? These are questions that people like Stephen Hawking have been working on for decades. It turns out that quantum information has a lot to give to answer these questions.
