qbraid-conversion

qbraid-conversion is a skill for Claude Code, Codex from xi-zhao/OpenQuantum. It costs 50 tokens per session (653 once invoked), scanned A, original, MIT.

A local qBraid workflow for converting structured unitary circuits between Qiskit and Cirq, two Python frameworks for building quantum circuits. It can export OpenQASM 2 and compare the resulting full unitary matrices.

In plain words
What is it for?
Use it to convert supported gate lists in either direction, preserve idle qubits, obtain OpenQASM 2 text, and run optional equivalence checks that ignore overall phase.
Why use it?
It helps move an existing circuit between frameworks while checking qubit order and mathematical equivalence. It avoids arbitrary code, cloud providers, measurements, resets, noise, and dynamic controls.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

qbraid-conversion scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (mcp/bridge.py, mcp/contracts.mjs, mcp/server.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

qBraid 本地电路转换

原生 SDK 路径

本能力同时支持 qBraid / Cirq 的原生公开 API。用户需要 程序类型、转换图、转译路径、序列化与供应商接口 时,由 Agent 在固定依赖环境中编写和运行任务代码,不限于下文便捷 Tool 的预设模型。

使用 node scripts/sdk-access.mjs inspect qbraid-conversion 定位环境,按完整 SDK 工作流执行。模块导航:qbraid、cirq、qiskit;导航不是 API 白名单。

下文关于模型、门集、输入与预算的限制描述便捷 Tool 的合同;原生 SDK 另受上游版本、可选依赖、宿主资源与用户授权约束。已禁用或被拒绝的动作不能借代码路径绕过。执行状态和科研验收分别报告。

调用 Harness 注册的 qbraid_local.convert_qbraid_circuit。适用于已有电路迁移与跨框架核对。

  • 提交 numQubits、结构化 gates 和 direction=qiskit-to-cirq|cirq-to-qiskit;旋转角单位为弧度,支持的门见 Tool schema。
  • 固定路径经过 OpenQASM 2;返回实际转换路径及可保存的 OpenQASM 2 文本。保留空闲量子位,q[i] 对应输入 i。
  • referenceMode=auto|required|skip;auto 在至 8 qubits 时比较完整酉矩阵,required 按请求运行,skip 保留未检查状态。比较忽略整体相位,独立对照包括导出文本重新解析后的结果。
  • 不接受任意 Python、文件路径、测量、重置、噪声或动态控制;不实例化云 Provider 或提交云任务。
  • 依赖须显式准备;计算仍可能写 SDK 缓存,保留 workspace-write;当前 L1,scientificValidation=not_evaluated。
  • qBraid 的同名 OpenQuantumProvider 面向 openquantum.com,不代表本仓库已接入该云服务。

安装、验证和限制。

依赖准备

运行前执行 node scripts/setup-paper-tools.mjs qbraid-conversion。缺失、旧锁和已安装环境的处理见共同准备说明;Tool 不自动安装或升级依赖。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

qbraid-conversion is a skill published in the GitHub repository xi-zhao/OpenQuantum (75 stars, last pushed yesterday), licensed MIT. It adds 50 tokens to every session and 653 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-25.
