fastdla.generators.hea.hea_generators(num_qubits)

Construct the generators of the hardware-efficient ansatz.

We adopt the definition of HEA in Larocca et al. Quantum 6 (2022):

\[\mathcal{G}_{\mathrm{HEA}} = \left\{ X_n, Y_n \right\}_{n=0}^{N_q-1} \cup \left\{ \sum_{n=0}^{N_q - 2} Z_n Z_{n+1} \right\}.\]

This set of generators are proven to close to a full rank DLA in the reference.
