Hamiltonian Simulation

Hamiltonian simulation evolves a state under e^(-iHt) - the one quantum method with a clear path to helping fusion, because it predicts how the low-activation materials Kronos builds its machines from behave under extreme conditions.

The concept

Simulating e^(-iHt) predicts how quantum systems evolve, where classical methods scale exponentially. Product formulas (Trotter-Suzuki) and qubitization make it efficient on quantum hardware.

How Kronos uses it

Kronos's first wall, centrepost, and blanket must survive years of 14 MeV neutron damage. Predicting the electronic structure and defect behavior of candidate low-activation alloys and plasma-facing materials is exactly where classical DFT struggles and quantum simulation should help first. KODEX keeps these workflows as a benchmarking track, validated on small molecules today.

Honest note

The tooling is real now; the decisive advantage on fusion-relevant molecules is expected around the mid-2030s. We build the pipeline so the science is ready when the hardware is.
