qrisp-arithmetic

qrisp-arithmetic is a skill for Claude Code, Codex from xi-zhao/OpenQuantum. It costs 41 tokens per session (758 once invoked), scanned A, original, MIT.

A local simulator for unsigned modular addition using Qrisp quantum registers. Modular addition wraps around at 2^n, where n is the register width, and the simulator can start from a fixed bit string or a uniform superposition.

In plain words
What is it for?
Use it to test fixed-width addition, inspect superposition outcomes, and examine the compiled circuit's qubit, depth, and gate counts.
Why use it?
It shows the output probabilities and circuit resource information without requiring a quantum device or cloud service. The wraparound behavior makes overflow expected rather than an arithmetic error.

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

qrisp-arithmetic 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

Qrisp 量子模加法

原生 SDK 路径

本能力同时支持 Qrisp 的原生公开 API。用户需要 量子类型、算术、控制结构、会话与编译 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 qrisp-arithmetic 定位环境,按完整 SDK 工作流执行。模块导航:qrisp;导航不是 API 白名单。

上游 EPL 许可与可选后端单独核对,不改变现有 MCP 默认关闭状态。

显式选择 JAX 数值精度和 target;需要 float64 时在建立数组前启用 jax_enable_x64。CPU、GPU 选择按任务与已安装后端决定。

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 qrisp_local 的 compute_qrisp_modular_sum。Skill 负责选择与解释,Tool 负责真实 SDK 执行。

输入 bitWidth、二进制 initialBits 与 addendBits;二进制串均为最高有效位在左,不得超过寄存器宽度。preparation=basis 编码指定整数;uniform 要求 initialBits 为零,再对全部数据位施加 H。

真实 Qrisp QuantumFloat 以逐位 X 门编码输入,再由整数保持的 gidney_adder 执行经典常数加法,结果是模 2^bitWidth 的环绕;例如宽度 3、110 加 011 得到 001。不要把溢出解释成计算错误。初始化、加数和输出标签均不经过浮点编码,能保留超过 2^53 的整数低位;输出位串保留精确整数标签。

outcomes 是 Qrisp 本地模拟概率;编译后的量子位、深度和门计数可能包含复合操作,不能当成某硬件的基础门成本。该接口不接受任意 Python 程序。

连接默认关闭,用户按需启用;依赖独立安装,采用上游 EPL-2.0 OR GPL-2.0 WITH Classpath-exception-2.0。当前不连接任何云供应商。

固定依赖需显式执行 node scripts/setup-paper-tools.mjs qrisp-arithmetic;调用时不安装依赖,数值库可能写入本地缓存。规模参数不按开发机算例设人工上限;通过独立的 execution 选择部署资源。

当前为 L1,scientificValidation=not_evaluated。成功执行与工程回归不代表科学 Acceptance。

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.

qrisp-arithmetic is a skill published in the GitHub repository xi-zhao/OpenQuantum (75 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 758 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 2026-09-29.
