ORBIT-Q: A new benchmark for evaluating autonomous coding agents in scientific quantum programming
By
[Submitted on 3 Jul 2026]
Summary
ORBIT-Q (Open Research Benchmark for Integrated Tasks in Quantum Computing) is a new dual-axis benchmark designed to evaluate autonomous coding agents in scientific quantum programming. Unlike conventional programming benchmarks, ORBIT-Q tests whether generated code preserves physical fidelity, differentiable workflows, framework-native semantics, and scalable representations. It combines a multi-tier verification pipeline supporting two comparisons: different agent configurations on a fixed quantum framework, and different quantum frameworks on a fixed agent. Evaluations found TensorCircuit-NG (TC) to be the most capable framework, and Codex with GPT-5.5 the strongest agent configuration on TC. However, a significant gap remains between autonomous agents and human expert implementations. The benchmark also evaluates agent-side resource use and artifact-side runtime efficiency.
