qutrunk-simulation

qutrunk-simulation is a skill for Claude Code, Codex from xi-zhao/OpenQuantum. It costs 37 tokens per session (717 once invoked), scanned A, original, MIT.

A local quantum-circuit simulator using QuTrunk's local backend. It returns OpenQASM, final complex amplitudes, and probabilities for an ideal circuit starting with all qubits at zero.

In plain words
What is it for?
Use it to run supported single- and two-qubit gates, inspect the generated OpenQASM 2 text, and examine every possible final bit pattern.
Why use it?
It provides circuit results without cloud services, GPUs, distributed computing, or quantum hardware. Its probabilities describe the calculated state rather than finite measurement counts.

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

qutrunk-simulation 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 4 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

QuTrunk 本地电路仿真

原生 SDK 路径

本能力同时支持 QuTrunk 的原生公开 API。用户需要 QCircuit、参数、门与上游后端 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 qutrunk-simulation 定位环境,按完整 SDK 工作流执行。模块导航:qutrunk;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。

Agent 经 Harness 调用 qutrunk_local 提供的 simulate_qutrunk_circuit。本 Skill 负责模型选择和结果解释,Tool 在独立 Python 环境执行真实上游 SDK。

输入 numQubits 和 gates。每项包括 gate、targets;支持 H/S/T/X/Y/Z/CX/CZ 和 RX/RY/RZ。旋转门必须提供 angle(rad),其他门不得提供。CX 的首个 target 是控制位。只接收结构化门,不执行用户代码或文件路径。

从全零态开始进行理想酉演化。outcomes 的位串左端是量子位 0,amplitude=[real,imag]。概率由 SDK 末态振幅计算,无裁剪或归一化。先检查 normError;概率不是有限 shots 测量频数。完整态向量的计算和存储随 2^N 增长。

显式选择 BackendLocal(run_mode="local"),不根据环境选择远程后端,不访问 QuSAAS、MPI 或 GPU。返回 program 是由 SDK Command 序列导出的 OpenQASM 2。固定 Python 3.10,因为 QuTrunk 0.2.2 声明 Python <3.11。SDK 内部量子位零在最低有效位,适配层已转换为输出左端位。

计算规模由调用方选择,后端数值表示限制仍适用。资源限制用 execution 设置,与模型参数分开。先运行 node scripts/setup-paper-tools.mjs qutrunk-simulation 显式准备固定依赖;计算调用不安装依赖或联网,数值库可能写本地缓存。

固定上游版本:0.2.2;来源与许可见上游仓库(Apache-2.0)。本地数值和协议检查属于开发证据;当前 L1,scientificValidation=not_evaluated,成功执行不等于最终科学 Acceptance。

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

qutrunk-simulation is a skill published in the GitHub repository xi-zhao/OpenQuantum (75 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 717 once invoked, about $0.0001 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 2026-09-28.
