<Function id="qiskit.ignis.verification.state_tomography_circuits" isDedicatedPage={true} github="https://github.com/qiskit-community/qiskit-ignis/tree/stable/0.7/qiskit/ignis/verification/tomography/basis/circuits.py" signature="state_tomography_circuits(circuit, measured_qubits, meas_labels='Pauli', meas_basis='Pauli')">
|
||
Return a list of quantum state tomography circuits.
|
||
|
||
This performs measurement in the Pauli-basis resulting in $3^n$ circuits for an n-qubit state tomography experiment.
|
||
|
||
**Parameters**
|
||
|
||
* **circuit** (`QuantumCircuit`) – the state preparation circuit to be tomographed.
|
||
* **measured\_qubits** (`QuantumRegister`) – the qubits to be measured. This can also be a list of whole QuantumRegisters or individual QuantumRegister qubit tuples.
|
||
* **meas\_labels** (`Union`\[`str`, `Tuple`\[`str`], `List`\[`Tuple`\[`str`]]]) – (default: ‘Pauli’) The measurement operator labels.
|
||
* **meas\_basis** (`Union`\[`str`, `TomographyBasis`]) – (default: ‘Pauli’) The measurement basis.
|
||
|
||
**Return type**
|
||
|
||
`List`\[`QuantumCircuit`]
|
||
|
||
**Returns**
|
||
|
||
A list containing copies of the original circuit with state tomography measurements appended at the end.
|
||
|
||
## Additional Information:
|
||
|
||
The returned circuits are named by the measurement basis.
|
||
|
||
To perform tomography measurement in a custom basis, or to generate a subset of state tomography circuits for a partial tomography experiment use the general function tomography\_circuits.
