Fully quantum time-lock puzzles
Open in the fully quantum case. Settled by the source paper when the generator is classical and the solver quantum, and when the generator is quantum and the solver classical under perfect completeness; a classical-query attack on the remaining cell would prove a simulation conjecture. 5 open

CAQB key agreement, imperfect completeness
Open. Settled for perfect completeness by the source paper’s Theorem 3.1; the argument’s final step uses perfect completeness in a way that no known weakening survives, and the paper’s Simulation-Conjecture barrier does not cover this party structure. 5 open

OWF minimality, non-black-box reductions
Open when the classical security implication is not witnessed by a black-box reduction between the two games. Settled affirmatively whenever it is, for uniform and non-uniform quantum adversaries alike, with the implementation reduction left arbitrary. 5 open

Polynomial Compatibility Conjecture
Open in the inverse-polynomial regime. Proved for exponentially small influences by the paper that introduced it, and false for influences at or above 1/(2d); everything between is what the quantum separations depend on. 5 open
