Claude designs quantum circuits that need fewer qubits and gates than the best published ones

Source: AnthropicAlso reported by QuEra Computing

Anthropic published research on 16 October 2026 in which Claude, given plain-language specifications and an automated evaluator, designed circuits for eight quantum computational primitives in chemistry, optimisation, physics simulation, number theory and numerical computing. In each case its designs used fewer qubits and fewer gates than the best previously published ones, in some cases by an order of magnitude or more; for elliptic-curve point addition a 53-hour run produced a design with 17 times fewer gates and 12% more qubits than the smallest previous design. The work was led by Andi Gu in Anthropic’s STEM Fellows Program with Susanne Yelin and Mikhail Lukin of Harvard University; QuEra Computing, where Lukin is co-founder, publicised it on 10 November.

Why it matters

Quantum algorithm designers get building blocks that need fewer qubits and gates, which lowers the hardware a useful fault-tolerant application requires.
