quantum-ground-state

quantum-ground-state is a skill for Codex from xi-zhao/OpenQuantum. It costs 103 tokens per session (1,043 once invoked), scanned A, original, MIT.

A narrowly defined quantum solver for the ground-state energy of a two-quantum-bit Pauli Hamiltonian in a specified one-excitation sector. It uses a noiseless statevector VQE and checks the result against an exact calculation; VQE is a method that searches for a low-energy quantum state.

In plain words
What is it for?
Use it to solve and validate supported two-quantum-bit Hamiltonians, compare VQE convergence with the exact reference, and create result or reproduction reports.
Why use it?
It limits the calculation to a problem that can be independently checked, separating the computed result from scientific acceptance.

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-ground-state 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 1mo ago.

The scan reads SKILL.md. This mod also ships 12 executable files (core/contracts.mjs, evals/run-evals.mjs, scripts/lib/canonicalize.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.

Quantum Ground State

能力边界

这个 Skill 只支持一个窄而可验证的科学主张：对用户提供的二量子位实 Pauli 和，在固定 hamming-weight=1 扇区内计算基态能量。执行方法固定为无噪 statevector VQE，并用独立的 实对称 2×2 闭式对角化提供参考。

把输入 Hamiltonian 当作用户提供的问题定义，不从名称或标签推断分子来源。 完整边界见 references/SCOPE.md，数值约定见 references/NUMERICAL-CONVENTIONS.md。

执行工作流

  1. 按 inputs/request.schema.json 检查结构，并由 solver 再做语义 preflight。
  2. 明确拒绝 QAOA、Pauli Y、复系数、错误单位、其他粒子扇区、更多量子位、shots 和噪声。
  3. 普通用户请求调用原生 Tool solve_and_validate_ground_state；它在一次确定性调用内生成六类事实并运行独立 Validator。
  4. facts-only 求解和已物化 Result Package 重验是内部 solver/Validator 接口，不增加到模型可见 Tool surface。
  5. 组合 Tool 自己的 provenance.complete 必须保持 not_checked；不得伪造 Session、路径或摘要让它通过。
  6. OpenQuantum 的可信 Host Plugin 从真实 Session/Tool 身份进入内部 Scientific Result Adapter； Materializer 使用 ctx.fs 物化、重读和校验 Result Package，Validator 只对重读后的结构化 证据产生 observations，central Acceptance Builder 再汇聚 Acceptance Profile、observations 和 provenance 推导科学结论。
  7. 需要评分或复现时，分别生成 Score Report 或 Reproduction Report；不得从运行完成推导它们。

本地事实求解命令：

node scripts/solve.mjs <request.json> <new-output-directory>

目标目录中任何同名 Artifact 已存在时必须拒绝覆盖。

产物合同

  • problem-spec
  • hamiltonian-manifest
  • exact-reference
  • ground-state-result
  • convergence-trace
  • resource-estimate

六类 Artifact 都是 additionalProperties: false 的 JSON 事实对象。不要在其中增加：

  • status、score、acceptance 或“已复现”结论；
  • Model 的主观置信度；
  • 没有来源链的分子/化学主张；
  • API key、凭证、绝对路径或 Harness 身份。

科学验收规则

权威规则位于 acceptance-profiles/supplied-pauli-statevector-v1.1.json。 当前请求使用 Profile 1.1.0，按请求预算检查资源使用；1.0.0 文件保留作历史记录。 1.6 mHa 只适用于这个 Profile，不是所有体系的普适标准。必须同时检查作用域、canonical digest、 Hermiticity、扇区不变性、精确参考重算、归一化、期望值回放、变分下界、收敛和 provenance。

若 optimizer 未收敛，solver 仍可产生有限事实，但 Validator 必须使必需的 vqe.converged 检查失败； 不得把它包装成科学成功。

解释要求

对用户解释时明确区分：这是“给定 Hamiltonian 的扇区基态”，不是完整的分子 Hamiltonian/FCI 工作流。 Model 可以解释 Result/Report，但不能修改中央 Acceptance Builder 基于 Validator observations、Profile 和 来源链推导的结论。

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-ground-state is a skill published in the GitHub repository xi-zhao/OpenQuantum (71 stars, last pushed today), licensed MIT. It adds 103 tokens to every session and 1,043 once invoked, about $0.0004 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 2026-08-30.
