Overview

Quantum circuit simulation

Choose a representation that matches the circuit, not the other way around.

Zi Humana does not force every workload through one data structure. Clifford-heavy studies stay in Ledger. Deep noisy circuits that still fit in memory use Statefold. Circuits with limited entanglement move to Lattice. Open systems move to Fieldline. Pauli-basis observable studies use PauliWeave.

Selection guide

Pure state, modest width: Statefold
Clifford plus a few non-Clifford layers: Ledger, then a bonded Statefold patch
Low entanglement, large width: Lattice
Lindblad or collapse dynamics: Fieldline
Operator spreading and truncated Pauli paths: PauliWeave

Select an engine

from zius.quantum import select_engine

engine = select_engine(
    num_qubits=20,
    noise=False,
    clifford_fraction=0.2,
)
print(engine.name)  # "lattice" or "statefold"
