pyriemann_qiskit.utils.hyper_params_factory.gen_two_local(reps=3, rotation_blocks=['ry', 'rz'], entanglement_blocks='cz')[source]

Return a callable that generate a TwoLocal circuit.

The two-local circuit is a parameterized circuit consisting of alternating rotation layers and entanglement layers [1].

Parameters:

  • reps (int (default 3)) – Specifies how often a block consisting of a rotation layer and entanglement layer is repeated.

  • rotation_blocks (str | list[str]) – The gates used in the rotation layer. Valid string values are defined in gates.

  • entanglement_blocks (str | list[str]) – The gates used in the entanglement layer. Valid string values are defined in gates.

Returns:

ret – An instance of a TwoLocal circuit.

Return type:

TwoLocal

Raises:

ValueError – Raised if rotation_blocks or entanglement_blocks contain a non valid gate.
