Statefold

Statefold

State-vector simulation for pure states that fit in memory.

Statefold keeps the full amplitude vector. It is the reference engine for Zi Humana studies that need exact unitaries: QAOA layers in the combinatorial programme, Bell-state counts, and small verification circuits used beside SMT proofs.

Pair it with the combinatorial research page when the circuit is an optimization ansatz rather than a general benchmark.
