# qiskit\_noise\_learning.experiment\_builder.VanillaInstructionSequences

*class* `qiskit_noise_learning.experiment_builder.VanillaInstructionSequences(*, prep_gate: ModelGate | None = None, meas_gate: ModelGate | None = None, gates: list[ModelGate] | None = None, coupling_map: CouplingMap | None = None, randomization_multiplier: int = 1)`

[GitHub](https://github.com/Qiskit/qiskit-noise-learning/tree/stable/0.1/qiskit_noise_learning/experiment_builder/stages/sequence_generators/vanilla_instruction_sequences.py)

Bases: [`AddInstructionSequences`](/docs/api/qiskit-noise-learning/generated/experiment-builder-add-instruction-sequences "qiskit_noise_learning.experiment_builder.stages.sequence_generators.add_instruction_sequences.AddInstructionSequences")

Generate vanilla instruction sequences for each target gate.

For each gate, generates 9 instruction sequences sufficient to measure any single- and two-qubit Pauli fidelity on a triangle-free coupling map.

**Parameters**

- **prep\_gate** – The preparation gate. If `None`, defaults to the gate named `"P"`.
- **meas\_gate** – The measurement gate. If `None`, defaults to the gate named `"M"`.
- **gates** – Gates to generate sequences for. If `None`, defaults to all non-SPAM gates.
- **coupling\_map** – The coupling map. If `None`, defaults to the gate set’s coupling map.
- **randomization\_multiplier** – Randomization multiplier applied to all generated sequences.

### required\_fields

Type: [`tuple`](https://docs.python.org/3/library/stdtypes.html#tuple)\[[`str`](https://docs.python.org/3/library/stdtypes.html#str), ...]

Built-in immutable sequence.

If no argument is given, the constructor returns an empty tuple. If iterable is specified the tuple is initialized from iterable’s items.

If the argument is a tuple, the return value is the same object.
