# openfermion.circuits.fermionic_simulation_gates_from_interaction_operator

Given $H = \sum_{I \subset [n]} H_I$, returns gates

$\left{G_I\right} = \left{e^{i H_I\right}$.

Each term $H_I$ is the sum of all terms in $H$ that involve exactly the orbitals $I$.

operator The interaction operator ($H$).

Returns: A dict from tuples of mode indices to gates.
