Driven time-dependent qubit Hamiltonian container.

class qdk_chemistry.data.time_dependent_qubit_hamiltonian.containers.driven.DrivenContainer(base_hamiltonian, drive_hamiltonian, drive)[source]

Bases: TimeDependentQubitHamiltonianContainer

Container for a driven Hamiltonian H(t) = H0 + f(t) * H1.

The Hamiltonian is split into a time-independent part H0 and a time-dependent part H1 whose coefficient is modulated by a scalar drive function f(t).

Parameters:

base_hamiltonian (QubitOperator) – Time-independent qubit operator.
drive_hamiltonian (QubitOperator) – Driven qubit operator (modulated by drive).
drive (Callable[[float], float]) – Scalar function f(t) that modulates drive_hamiltonian.

Raises:

ValueError – If base_hamiltonian and drive_hamiltonian have different qubit counts.

__init__(base_hamiltonian, drive_hamiltonian, drive)[source]

Initialize the driven container.

Parameters:

base_hamiltonian (QubitOperator)
drive_hamiltonian (QubitOperator)
drive (Callable[[float], float])

Return type:

None
