A Suggested reading for quantum information applications in QFT

What would you say is essential reading for those of us who want to understand how exactly is QFT benefiting from QI?
Can anyone give a summary of what is happening, and where to start reading? (at postgraduate/entry-research-level).

Entanglement harvesting is a topic that comes to my mind ...
 
Some nice lectures I've found on the cross section of quantum field theory, quantum info, and quantum gravity:
Dan Harlow's Jerusalem lectures: https://arxiv.org/abs/1409.1231
Tom Hartman's course on "Quantum gravity and black holes": http://www.hartmanhep.net/topics2015/

I guess these are both relatively old compared to how fast the field moves though, so they might be more geared towards someone who was a grad student in 2016 like I was :).

Thread 'The Power of QM and QFT'

We often see discussions about what QM and QFT mean, but hardly anything on just how fundamental they are to much of physics. To rectify that, see the following; https://www.cambridge.org/engage/api-gateway/coe/assets/orp/resource/item/66a6a6005101a2ffa86cdd48/original/a-derivation-of-maxwell-s-equations-from-first-principles.pdf 'Somewhat magically, if one then applies local gauge invariance to the Dirac Lagrangian, a field appears, and from this field it is possible to derive Maxwell’s...

Thread 'Importance of Hanbury Brown and Twiss experiment'

I read Hanbury Brown and Twiss's experiment is using one beam but split into two to test their correlation. It said the traditional correlation test were using two beams........ This confused me, sorry. All the correlation tests I learnt such as Stern-Gerlash are using one beam? (Sorry if I am wrong) I was also told traditional interferometers are concerning about amplitude but Hanbury Brown and Twiss were concerning about intensity? Isn't the square of amplitude is the intensity? Please...

Thread 'Prof Mike Wiest's proposed link between quantum and consciousness'

I am not sure if this belongs in the biology section, but it appears more of a quantum physics question. Mike Wiest, Associate Professor of Neuroscience at Wellesley College in the US. In 2024 he published the results of an experiment on anaesthesia which purported to point to a role of quantum processes in consciousness; here is a popular exposition: https://neurosciencenews.com/quantum-process-consciousness-27624/ As my expertise in neuroscience doesn't reach up to an ant's ear...
