qiskit_noise_learning.utils.build_with_prep_noise

qiskit_noise_learning.utils.build_with_prep_noise(circuit: QuantumCircuit, prep_noise_ref: str = 'prep', prep_modifier_ref: str = '') → tuple[QuantumCircuit, Samplex]

Build a template circuit with injectable preparation noise.

This function uses the normal samplex build path except adds an additional node for injectable preparation noise at the beginning of the circuit.

Parameters

• circuit – The annotated circuit to build.
• noise_ref – The name of the reference to the noise map.
• modifier_ref – The name used for the argument to modify the rates of the noise map.

Returns

The template circuit and the samplex.

Raises

ValueError – If the circuit does not begin with a left-dressed twirl annotated box.
