A Suggested reading for quantum information applications in QFT

Click For Summary
Essential reading for understanding the intersection of quantum field theory (QFT) and quantum information (QI) includes Dan Harlow's Jerusalem lectures and Tom Hartman's course on quantum gravity and black holes. These resources provide foundational insights into how QFT benefits from QI, particularly in areas like entanglement harvesting. While these materials may be somewhat dated, they remain relevant for postgraduate students and early researchers. The discussion highlights the rapid evolution of the field, suggesting that newer resources may also be necessary for comprehensive understanding. Engaging with these lectures can enhance comprehension of the complex relationship between QFT and QI.

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 'Angular Momentum Vector and Its Magnitude'

For the quantum state ##|l,m\rangle= |2,0\rangle## the z-component of angular momentum is zero and ##|L^2|=6 \hbar^2##. According to uncertainty it is impossible to determine the values of ##L_x, L_y, L_z## simultaneously. However, we know that ##L_x## and ## L_y##, like ##L_z##, get the values ##(-2,-1,0,1,2) \hbar##. In other words, for the state ##|2,0\rangle## we have ##\vec{L}=(L_x, L_y,0)## with ##L_x## and ## L_y## one of the values ##(-2,-1,0,1,2) \hbar##. But none of these...
