The real obvious killer app for quantum computers is simulating quantum systems. You can build your way up surprisingly far just from the fundamental quantum description. The calculational complexity of doing that is one of the major reasons why we're interested in building quantum computers. James McCrell: I've read many articles and listened to many discussions that lead me to wonder what is meant by the cosmos being a computer program made by some master programmer. Please decipher are those describing actual processes or is all of this talk an attempt to describe the cosmos in understandable terms?
Welcome to the December 2022 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic. Enjoy!
Remember that I take a holiday break at the end of the year, so the next AMA will be at the beginning of February.
