Convert Qamomile Hamiltonians to Amazon Braket observables.

def hamiltonian_to_braket_observable(hamiltonian: qm_o.Hamiltonian) -> 'Observable'

Convert a Qamomile Hamiltonian to a Braket observable.

A scalar-only Hamiltonian is represented on qubit zero because Braket observables always address at least one qubit. The executor evaluates such Hamiltonians locally and does not add that synthetic qubit to a task.

Parameters:

Returns:

'Observable' — Native Braket observable, including all coefficients.

Raises:

• ValueError — If a coefficient has a non-negligible imaginary part.
