Creates an Efficient SU2 variational quantum circuit.

This function generates a parameterized quantum circuit based on the Efficient SU2 ansatz. The circuit consists of alternating layers of rotation gates and entanglement operations.

Parameters:

  • num_qubits (int) – The number of qubits in the circuit.

  • rotation_blocks (list[str] | None) – A list of rotation gates to apply in each rotation layer. If None, defaults to [“ry”, “rz”].

  • entanglement (str) – The type of entanglement to apply. Options are ‘linear’, ‘full’, ‘circular’, or ‘reverse_linear’.

  • skip_final_rotation_layer (bool) – If True, skips the final rotation layer.

  • reps (int) – The number of repetitions of the rotation-entanglement block.

Returns:

The constructed Efficient SU2 variational quantum circuit.

Return type:

qm_c.QuantumCircuit

Raises:

NotImplementedError – If an unsupported rotation gate or entanglement type is specified.

Example

>>> circuit = create_efficient_su2_circuit(3, rotation_blocks=["rx", "ry"], entanglement="full", reps=2)
