AI Thread Summary

The discussion centers on solving two challenging problems related to GHZ (Greenberger-Horne-Zeilinger) states in three-qubit quantum systems. The original poster expresses frustration after spending an entire day on these problems without success. A moderator has moved the thread to an advanced physics homework forum for better assistance. A user requests the poster to share relevant equations and any attempts made at finding a solution. The conversation highlights the need for collaboration and sharing of information to tackle complex quantum state problems.

@MattiaBosco please post whatever relevant equations you have and what attempts you have made at a solution.

Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
