iqm.benchmarks.compressive_gst.mgst.qiskit_interface.add_idle_gates(gate_set: list[IQMCircuit], active_qubits: list[int], gate_qubits: list[list[int]]) → list[IQMCircuit]#

Add additional idle gates to a gate set.

Each gate in the output gate_set acts on exactly the number of qubits on which the GST experiment ist defined. For instance if the GST experiment is supposed to be run on qubits [0,1,2], then a X-Gate on the 0-th qubit turns into X otimes Idle otimes Idle. This representation is needed for the internal handling in mGST.

Parameters:

  • gate_set (list[IQMCircuit]) – Each element is a gate to be used for GST, stored as a circuit.

  • active_qubits (list[int]) – Specifies the list of qubits on which GST-circuits are run.

  • gate_qubits (list[list[int]]) – The i-th elements in the active_qubit list specifies on which qubits the original i-th gate in the input gate set is supposed to act.

Returns:

The output gate set with added idle gates.

Return type:

list[IQMCircuit]
