qiskit.ignis.characterization.t1_circuits

t1_circuits(num_of_gates, gate_time, qubits)

Generate circuits for T1 measurement.

Each circuit consists of an X gate, followed by a sequence of identity gates.

Parameters

• num_of_gates (Union[List[int], array]) – the number of identity gates in each circuit. Must be in an increasing order.
• gate_time (float) – time of running a single identity gate.
• qubits (List[int]) – indices of the qubits whose T1‘s are to be measured.

Return type

Tuple[List[QuantumCircuit], array]

Returns

• Generated circuits
• Delay times, i.e., gate_time multiplied by the numbers in num_of_gates
