Quantum Simulations for Molecular DesignMaturity: concept

Electronic-structure and molecular-interaction simulation for candidate design and screening.

concept An idea we find credible. Nothing has been built or measured.

What this is

The problem

Predicting how a molecule behaves — its electronic structure, how it binds, how it reacts — is the foundation under drug discovery, catalysis and materials. Accuracy and cost trade against each other steeply.

Where the current approach strains

Density functional theory is the workhorse and is remarkably good, but it has known blind spots: strongly correlated systems, transition-metal chemistry, excited states. Those blind spots overlap uncomfortably with the interesting problems.

What we are exploring

Simulation of electronic structure and molecular interaction for small, strongly-correlated systems where classical approximation is weakest — the narrow band where quantum methods have the clearest theoretical case.

What would have to be true

Agreement with high-accuracy classical results on systems small enough that both can be run. That is the only honest starting point: match the known answer before claiming the unknown one.
