Data Format

Each JSON file contains an array of problem sets. Every problem set follows this schema:

{
    "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"
}

All mathematical notation is written in LaTeX.
