quantum-guide-algorithms-search

quantum-guide-algorithms-search is a skill for Claude Code from xi-zhao/OpenQuantum. It costs 33 tokens per session (558 once invoked), scanned A, original, MIT.

A guide for quantum search examples and their open-source implementations. It covers quantum walks on linked trees and a specific hidden-shift problem, where a hidden change must be recovered from oracle queries.

In plain words
What is it for?
Use it for the glued-trees quantum walk or for even-bit quadratic bent-function hidden-shift circuits.
Why use it?
It prevents a broad search request from being matched to an unsupported problem type. The listed examples also state their limits instead of assuming a general speedup.

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

quantum-guide-algorithms-search 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.

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

本地开源适配。上游指南 ID:algorithms/search。

分类导航:保留用户显式调用;自动任务直接选择叶子方法 Skill,或使用 quantum-algorithms 查找。

选择工作流

按用户的数学问题、输入表示、计算规模和需要的输出选择一个叶子 Skill。知识解释可直接使用原理;计算任务加载叶子 Skill,使用其中的开源实现和现有代码执行 Tool。无需为阅读指南启动额外服务。

  • quantum-glued-trees:随机交替叶环连接的双树连续时间邻接矩阵量子行走;稠密编译和出口概率,不宣称搜索加速。
  • quantum-hidden-shift:偶数位二次 bent 函数的 shifted/dual 相位 oracle;其他函数族需要另写任务代码。

全量条目见覆盖表。如果用户描述跨领域,按实际依赖组合相关叶子 Skill;不要要求用户先阅读整条目录链。

来源与边界

上游 MIT 指南:algorithms/search。原文作为参考保存在固定检索库,本文件将执行路线改为开源 SDK。来源摘要和算法模块对应关系见coverage.json,许可证与改动说明见NOTICE。

自定义 SDK 程序

示例用于解释和接口核验,不是可执行任务的边界。用户需要其他模型、数据、算法步骤、梯度或后端时,按原生 SDK 工作台在固定环境中编写并执行自定义代码;由 Agent 完成程序与工件交付。使用 quantum-algorithms 环境定位相关 SDK,保留本算法的数学假设与数值误差说明。

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.

quantum-guide-algorithms-search is a skill published in the GitHub repository xi-zhao/OpenQuantum (75 stars, last pushed yesterday), licensed MIT. It adds 33 tokens to every session and 558 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 2026-09-25.
