| ## Data Format |
|
|
| Each JSON file contains an array of problem sets. Every problem set follows this schema: |
|
|
| ```json |

| "topic": "Problem title", |
| "level": "graduate", |
| "describe": "Problem description and context (LaTeX)", |
| "tags": ["POVM", "state-discrimination", "quantum-measurement"], |
| "source": { |
| "institution": "Caltech & TU Delft", |
| "course": "CS/Ph 120 — Quantum Cryptography", |
| "license": "Academic use — original course materials", |
| "url": "https://..." |
| }, |
| "questions": [ |
| { |
| "question": "Question text (LaTeX)", |
| "solution": "Solution/answer (LaTeX)", |
| "difficulty": "hard", |
| "problem_type": "proof", |
| "prerequisite_knowledge": ["linear algebra", "density matrices", "POVM"], |
| "tags": ["pretty-good-measurement", "POVM"] |
| } |
| ], |
| "date": "DD.MM.YYYY", |
| "author": "Author name(s)", |
| "license": "Institution name" |
| } |
| ``` |
