Designing more efficient quantum circuits with Claude

Anthropic's Claude has demonstrated the ability to design more efficient quantum circuits, outperforming previously published algorithms. Given plain-language specifications for eight circuits across chemistry, optimization, physics simulation, and number theory, Claude worked in a closed loop with an automated evaluator. It proposed designs, received feedback, and iteratively improved its attempts without human intervention between rounds. This process led to novel designs that significantly reduced the required quantum resources, potentially accelerating the arrival of practical quantum computers.

Unlike previous methods, Claude improved on the best published circuits, in some cases by an order of magnitude or more, by working in a closed loop with an automated evaluator.
