GPT-5.6 Sol Ultra helped solve a six-year-old open problem in quantum cryptography by generating the construction and main proof ideas through Codex. ...

AI usage. The human authors take full responsibility for the claims and pr[oofs] and have carefully refined and verified them. The construction and main idea[s were generate]d entirely by Codex using GPT 5.6 Sol Ultra, using harness ideas generated [by] [UCLA?] Moonshot Harness [ZHC+26] and [Ope26].
