The Pipeline: LaTeX → IR → Backend

Write in LaTeX:           Parse to IR:              Compile to Backend:
───────────────────────  ────────────────────────  ────────────────────
H = ω σ_z +              HamiltonianIR             QuTiP Qobj
    A cos(ωt) σ_x    →   - terms: [...]       →   NumPy array
    + c_ops         - free_symbols: {ω, A}       JAX function
                      - time_dependent: True      Custom backend

Key Features:

  • ✅ Physics-style LaTeX input

  • ✅ Multiple backends (QuTiP, JAX, NumPy, custom)

  • ✅ Time-dependent Hamiltonians & collapse operators

  • ✅ Transparent intermediate representation (IR)

  • ✅ Open-system support

  • ✅ Boson deformations & custom subsystems
