Functions

magnus

Dispatch Magnus to the appropriate backend based on device of the given array.

API

magnus(tlist: qcheff.operators.operator_base.qcheff_array, drift_ham: qcheff.operators.qcheffOperatorMatrix, control_sigs: qcheff.operators.operator_base.qcheff_array, control_hams: collections.abc.Sequence[qcheff.operators.qcheffOperatorMatrix])

Dispatch Magnus to the appropriate backend based on device of the given array.

Parameters

tlist : np.ndarray Time list. drift_ham : np.ndarray or cp.ndarray Drift Hamiltonian. control_sigs : np.ndarray Control signals. control_hams : np.ndarray or cp.ndarray Control Hamiltonians.

Returns

magnus_class : MagnusTimeEvolDense or MagnusTimeEvolSparseLazy An instance of the appropriate Magnus class based on the sparsity of the drift Hamiltonian.
