These results build on a research collaboration between Anthropic and Harvard where Claude Mythos 5 outperformed established benchmarks on seven of eight quantum circuit design tasks. The model operated in a closed loop using the OpenEvolve tool to propose architectures and refine them based on an automated evaluator. This work included the first reversible implementation of the divsteps algorithm, which reduces the resources required for quantum applications in materials science and chemistry.

Claude Debunks 25 Year NSA Backdoor Theory on NIST Seeds
AI4 days ago
The Claude AI model identified the specific origin of the NIST P-256 seed in less than 30 minutes, providing mathematical evidence that resolves 25 years of speculation that the NSA hid a backdoor in the curve seeds. The model found the seed was candidate #1842 from a random number generator that started at 01:52:34 UTC on August 16, 1997. In a separate development, independent researchers improved an elliptic curve quantum circuit design by Anthropic, reducing the gate count to 11.9M at 843 qubits compared to Claude's 21M gates.
