mindquantum.utils.random_hamiltonian

mindquantum.utils.random_hamiltonian(n_qubits: int, n_terms: int, seed: int = None, dtype=None)

Generate a random Pauli Hamiltonian.

Parameters

• n_qubits (int) – Number of qubits

• n_terms (int) – Number of Pauli terms

• seed (int, optional) – Random seed. Defaults to None.

• dtype (mindquantum.dtype) – data type of hamiltonian. Default: None.

Returns

Hamiltonian, Randomly generated Hamiltonian

Examples

>>> ham = random_hamiltonian(4, 5, seed=42)
>>> print(ham)
