QH-GEM: Quantum-Hydrodynamic Generative Modeling
A preprint on arXiv introduces QH-GEM, a generative model that uses the Born probability density from the free-particle Schrödinger equation as the output distribution. The approach evolves the Madelung hydrodynamic equations from an initial reference density and a controllable phase function, yielding a deterministic generative process.

QH-GEM could be implemented as a classical differential-equation-based generative model and benchmarked against normalizing flows or diffusion models within two years.
The Madelung system is a set of deterministic PDEs that can be discretized with existing differentiable solvers, and the initial phase can be parameterized by a neural network and optimized with standard generative training objectives. This reuses infrastructure from neural ODEs and physics-informed machine learning, so a proof-of-concept benchmark is plausible if the optimization remains stable.
