Did some digs in the past on alternative theories, i don't think it has anything to do with the DOE and Q clearance to be honest, the most interesting ones i found

Q stands also for Quest, that's the engine on top of which almost every chess game and AI systems designed to play are based on https://www.chessprogramming.org/Quest

If you are interested have a look at this thread on the topic (made it few months ago but was a dig on Q, possible relations with AI, Chess, and IBM DeepBlue) https://greatawakening.win/p/11S0lBJVxv/qcheckmatefritz-and-ibmpossible-/

Q in Chess stands for Queen - We saw many times Melania with references also on the Lockwood tales and many suspected she may have been involved deeply

Q could be Quantum - this goes somehow back to the Quest point, could be a sorta of game theory AI parsing tons of data with a the team behind who are the 10 said ones in the know

Quantum part 2 - Other side of Quantum is the metaphysical, not an item in with which many may look or want to hear, but Q himself spoke about battles being being fought not only on this planet / reality, this opens you different options, time travel, astral projection, remote viewing, and much more, there's a book on the Q Metaphysics (yes, the theory is called Q), and that talks about the Great Awakening, name is Q Metaphysics: The End Of Deception, The Rebirth Of Humanity

Q is the name for ancient missing documents on top of which endless search attempts have been made to find them but without success, seems that, who has those documents, could flip the entire narrative <-- this is the last dig i did and that i should still continue together with the previous, it has actually some interesting possible links with the bloodline stories of the DS and DJT or someone within the white hats that may have those docs
