Return a normal ordered QuadOperator corresponding to single term.
openfermion.transforms.normal_ordered_quad_term( term, coefficient, hbar=1.0 )
||A tuple of tuples. The first element of each tuple is an integer indicating the mode on which a boson ladder operator acts, starting from zero. The second element of each tuple is an integer, either 1 or 0, indicating whether creation or annihilation acts on that mode.|
||The coefficient of the term. hbar (float): the value of hbar used in the definition of the commutator [q_i, p_j] = i hbar delta_ij. By default hbar=1.|
|ordered_term (QuadOperator): The normal ordered form of the input. Note that this might have more terms.|
In our convention, normal ordering implies terms are ordered from highest tensor factor (on left) to lowest (on right). Also, q operators come first.
