merlin-learning SKILL.md skillA
merlin-learning from xi-zhao/openquantum is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add xi-zhao/openquantum/merlin-learning@git:20261012.5ce3b3ePins git:20261012.5ce3b3e in mdr.lock. Pin the fingerprint instead.

用 Quandela MerLin 在 CPU 上批量计算无损光子线路的完整 Fock 概率，以及指定输出概率对相移的自动微分梯度。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MerLin 光子层推断与梯度 <!-- BEGIN NATIVE SDK ACCESS --> ## 原生 SDK 路径 本能力同时支持 **MerLin 的原生公开 API**。用户需要 自定义光学电路、QuantumLayer、测量策略与 Torch 训练 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 merlin-learning` 定位环境，按[完整 SDK 工作流](../quantum-sdk-workbench/references/workflow.md)执行。模块导航：`merlin`、`perceval`；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。 <!-- END NATIVE SDK ACCESS --> Agent 经 Harness 调用 `merlin_local` 的 `evaluate_merlin_layer`。用于分析光子量子层的可微响应；完整训练模型、准确率对比和实机推断需要其他工作流与证据。 输入模式数、Fock `occupation`、目标 `targetOccupation`、`BS`/`PS` 操作序列及二维 `phases`。每个 phase 行是一次参数取值，各列按线路中 PS 出现的顺序绑定。`BS.theta` 使用 Perceval Rx 约定：对角元 cos(theta/2)，非对角元 i sin(theta/2)；所有角度为弧度。目标与输入光子总数必须相同；MerLin SLOS 后端要求输入至少一个光子。每条线路至少有一个 PS，参数可跨批次比较。 Tool 显式使用完整 `FOCK` 空间而非 MerLin 默认的 `UNBUNCHED` 空间，保留光子聚束事件且不进行后选择。返回 `basis` 明确列出概率列对应的模式占据数；`phaseGradients` 是对应批次的目标输出概率对各 PS 角度的偏导，采用 CPU float64 自动微分。检查 `probabilitySums`，并用有限差分检验关键参数点；目标梯度不代表模型精度提升或量子优势。模拟假定光子不可区分、理想无损器件，无有限 shots 统计噪声。 …

How to install
mdr add xi-zhao/openquantum/merlin-learning@sha256:541848435fe1abf8The line at the top of this page pins the label git:20261012.5ce3b3e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
