SI found more economical ways to compute on a quantum computer; this still has to be tested on real hardware.
According to Anthropic, the Claude Mythos 5 model, together with researchers from Harvard and QuEra Computing, worked in a closed loop: it proposed a circuit, an automatic evaluator checked correctness and counted operations and qubits, and the model then reworked the circuit. In eight tasks from chemistry, optimisation, physics simulation and number theory, the authors say, seven circuits use fewer operations and qubits than the best published algorithms; one elliptic-curve point-addition circuit uses 17 times fewer operations, and a decoder for Decoded Quantum Interferometry roughly 12 times fewer costly operations. The elliptic-curve work took 53 hours with minimal human involvement. The authors' caveats: these are circuit designs and resource estimates, not runs on quantum hardware, and the baseline circuits used for comparison differ between tasks. The preprint is arXiv:2610.22367.
