qat.fermion.circuits.make_compressed_ldca_circ

qat.fermion.circuits.make_compressed_ldca_circ(nb_fermionic_modes: int, ncycles: int, eigstate_ind: Optional[int] = 0, slater: Optional[bool] = False) → Circuit

Builds a compressed version of the LDCA ansatz circuit.

The new pattern was obtained using qat.synthopline.

Parameters

• nb_fermionic_modes (int) – Number of qubits.

• ncycles (int) – Number of LDCA cycles.

• eigstate_ind (Optional[int]) – Eigenstate index. Defaults to 0.

• slater (Optional[bool]) – Whether to only include excitation-preserving rotations. Defaults to False.

Return: Circuit
