Unforgeable so far. Unbreakable... so far. No vulnerability... so far.

Nah, these things are soundly unforgeable and unbreakable because you can only ever read them once. Any measurements will alter the state and be detected and this occurs in a fundamental way due to how the universe works.

They have not been used so far, so nobody poured a ton of effort into developing an attack. People have thought that something is safe a lot of times.
