@TOEwithCurt At a 2022 conference, Renner applied the thought experiment to Everettian theory, showing that a quantum agent might not have a continuous notion of memory. I tried to unpack this here, in case it’s useful to others thinking about these issues: arxiv.org/abs/2406.06719

Some of Renato Renner's own PhD students refused to work on his result because it disturbed their sense of self. What he proved (with Frauchiger): quantum mechanics, applied consistently to the physicists who use it, generates flat contradictions… for the quantum observers themselves. Renner himself went from many-worlds to QBism to what he calls "no man's land." curtjaimungal.com

Despite the hurdles this year, I'm grateful for the hard work and dedication of all the students and collaborators.

Relative Descriptors for Quantum Agents arxiv.org/abs/2406.06719 Together with undergrad student Lorenzo, we examined the Frauchiger-Renner thought experiment in the context of Everettian quantum theory. Currently under review.

Thread: Reflecting on 2024 🧵 This year has been challenging for Porto Alegre, with a historic flood impacting our community. Despite these difficulties, our eclectic team managed to achieve several milestones in our research. Here’s a summary of what we accomplished:

@CABedardPhysics Thanks for sharing! I'll enjoy reading it. I just posted a rudimentary version of my lecture notes here (zenodo.org/doi/10.5281/ze…), incorporating several ideas I learned from your papers. If you happen to glance over it, any critique would be very welcome.
