Which assets fail together: the network’s response, simulated past the classical limit
The response of a 156-node network simulated to eight time steps on a 156-qubit processor; the classical simulator we ran stopped at six. For a planner, that is the contingency case read further than the reference tool reaches.
Headline result
8 steps vs 6
eight time steps at high significance on 156 qubits, in three minutes

01 · The decision
The decision on the table
When a line trips, which assets fail together and where the stress concentrates is answered today by contingency analysis run case by case on a simplified model. The full coupled response is what a planner needs and what the reference simulator runs out of.
02 · What we did
What we did, with proprietary methods
The network was simulated as one coupled system on the whole processor, at the same circuit depth for every time step, and the response measured step by step. The classical simulator was run on the same problem to find where it stops.

For a client, the next step is the first engagement on this page’s industry: you send one expansion case, as a network file with in-service status honoured. You get back the proven plan and the gap. Two weeks.
