Working autonomously in a closed loop with an automated evaluator, the model improved qubit and gate efficiency by up to an order of magnitude in some cases. The work, led by Andi Gu under Anthropic’s STEM Fellows Program, involved collaboration with Harvard researchers Susanne Yelin and Mikhail Lukin, as well as Alek Kemeny from Anthropic. A 46-page companion paper submitted to arXiv details an evolutionary framework where Claude proposes designs, an evaluator verifies them, and the model iterates without human input between rounds.\n\nKey improvements include a reversible modular-inversion algorithm for elliptic-curve arithmetic—saving 12% qubits while reducing gates by 17x—and a 12-fold optimization of a quantum decoder for optimization problems. Anthropic notes Claude’s cautious approach, which sometimes delayed progress but led to rigorous proofs. The results suggest AI could accelerate quantum circuit design, potentially optimizing entire quantum systems for specific tasks.","keyPoints":["Claude Mythos 5 redesigned quantum circuits for eight tasks, improving qubit/gate efficiency by up to an order of magnitude","Two breakthroughs: a reversible modular-inversion algorithm and a 12x faster quantum decoder for optimization","Work involved 53 hours of autonomous iteration with minimal human input, led by Andi Gu and collaborators"],"whyItMatters":"These results demonstrate AI’s potential to autonomously innovate in quantum computing, reducing barriers to practical quantum algorithms.
