QuimbSimulator¶

class QuimbSimulator(quimb_circuit_factory, autodiff_backend=None, progbar=False)[source][source]¶

Bases: TensorNetworkSimulationSettings

Settings for Quimb simulator.

This is compatible with both Quimb’s MPS simulator, which eagerly contracts gates by default, as well as Quimb’s standard method for circuit simulation.

Example usage:

from functools import partial
import quimb.tensor
from qiskit_addon_aqc_tensor.simulation.quimb import QuimbSimulator

simulator_settings = QuimbSimulator(
    partial(
        quimb.tensor.CircuitMPS,
        gate_opts={"cutoff": 1e-8},
    ),
    autodiff_backend="jax",
)

For additional options, see the API documentation for quimb.tensor.Circuit and quimb.tensor.CircuitMPS.

Attributes

Parameters:

quimb_circuit_factory (QuimbCircuitFactory)
autodiff_backend (str | None)
progbar (bool)

autodiff_backend: Optional[str] = None¶

progbar: bool = False¶: Whether to display a progress bar while applying gates.

quimb_circuit_factory: QuimbCircuitFactory¶: Callable for constructing the Quimb circuit, e.g., Circuit() or CircuitMPS().
