Your kidding me right? Q-Clearance is a real thing, part of the DOE. It's the top most level security clearance available. There's even a wiki about it:
https:// en.wikipedia.org/wiki/Q_clearance
>Anyone possessing an active Q clearance is always categorized as holding a National Security Critical-Sensitive position (sensitivity Level 3).[1] Additionally, most Q-cleared incumbents will have collateral responsibilities designating them as Level 4: National Security Special-Sensitive personnel.[2] With these two designations standing as the highest-risk sensitivity levels, occupants of these positions hold extraordinary accountability, harnessing the potential to cause exceptionally grave or inestimable damage to the national security of the United States.
