Could you build this?
No Differentiable quantum chemistry requires advanced theoretical quantum physics, specialized linear algebra, and deep research knowledge of automatic differentiation in molecular electronic structures.
What it would actually take: The stack typically relies on high-performance scientific frameworks like JAX, PyTorch, or Julia, integrating molecular orbital theory, Hartree-Fock, or Density Functional Theory (DFT) with reverse-mode automatic differentiation. The challenging core lies in numerically stable gradient tracking through self-consistent field (SCF) iterations and continuous basis-set integrations. Building this requires specialized academic research in theoretical chemistry and scientific computing.
Discussion
15 comments analyzed.
Competitors mentioned: Molpro, Molecular dynamics simulations, Other DFT software packages
Concerns raised: Hartree-Fock inaccurate for molecular interactions (e.g., Van Der Waals forces), O(n^4) scaling limits to ~10 atoms currently, Memory/runtime constraints for larger molecules, Quantum chemistry field lacks clarity on fundamental vs. computational approximations
Feature requests: Support for density functional theory (DFT) method, Scale to ~50 atoms with density fitting optimization, Model chemical reactions and molecular interactions, Handle complex molecules like amino acids
