## Anthropic's Claude Model
Anthropic reported Claude designed quantum circuits that outperform best published work across eight tasks.
## Research Team
Led by Andi Gu with mentorship from Alek Kemeny and collaboration with Harvard researchers Susanne Yelin and Mikhail Lukin.
## Quantum Computing Challenge
Current quantum computers have hundreds to thousands of qubits that are highly sensitive to noise.
## FeMoco Molecule
FeMoco molecule reduced gate counts 150,000-fold over eight years through multiple research groups.
## Claude's Workflow
Claude received plain-language specs for eight computational primitives and designed circuits in Python with automated checks.
## Elliptic-Curve Point Addition
Claude solved modular inversion in 53 hours using 12% more qubits but 17x fewer gates than previous designs.
## Quantum Interferometry
Claude reduced decoder gate count 12-fold by replacing extended Euclidean algorithm with Berlekamp-Massey decoding.
## Next Steps
Anthropic plans to use AI to optimize every layer of error-corrected quantum computers jointly.
## Key takeaway

Anthropic's Claude model created quantum circuits that use 17x fewer gates than previous designs for elliptic-curve point addition.
