RAF III is clearly following the papers on the arXiv in some detail so he was able to see the PhD thesis by Jennifer Lin,
Also, RAF III was able to notice that the thesis refers to a 2013 TRF blog post. I assure you, it's not usual to cite blog posts and the technical author needs some balls to do a thing like that in an otherwise formally flawless technical piece of work. Thanks for that, Jennifer!
Jennifer cites my blog post as the first source of the observation that the "existence or non-existence of a [non-traversable] wormhole in quantum gravity" is not observable by a well-defined apparatus or a procedure; and, correspondingly, it is not an observable in the theoretical sense (i.e. a linear Hermitian operator). This negative statement has to hold because the "existence of entanglement", which is dual to it, isn't an observable, either.
