If non-default values are used gate_lengths should be a list of tuples ``(name, qubits, value)`` where ``name`` is the gate name string, ``qubits`` is either a list of qubits or ``None`` to apply gate time to this gate one any set of qubits, and ``value`` is the gate time in nanoseconds. The resulting errors may contains two types of errors: gate errors and relaxation errors. The gate errors are generated only for ``Gate`` objects while the relaxation errors are generated for all ``Instruction`` objects. Exceptionally, no ``QuantumError`` s are generated for ``Measure`` since ``ReadoutError`` s are generated separately instead. Args: properties (BackendProperties): device backend properties. gate_error (bool): Include depolarizing gate errors (Default: True). thermal_relaxation (Bool): Include thermal relaxation errors (Default: True). If no ``t1`` and ``t2`` values are provided (i.e. None) in ``target`` for a qubit, an identity ``QuantumError` (i.e. effectively no thermal relaxation error) will be added to the qubit even if this flag is set to True. If no ``frequency`` is not defined (i.e. None) in ``target`` for a qubit, no excitation is considered in the thermal relaxation error on the qubit even with non-zero ``temperature``. gate_lengths (list): Override device gate times with custom values. If None use gate times from backend properties. (Default: None). gate_length_units (str): Time units for gate length values in ``gate_lengths``. Can be 'ns', 'ms', 'us', or 's' (Default: 'ns'). temperature (double): qubit temperature in milli-Kelvin (mK) (Default: 0). warnings (bool): DEPRECATED, Display warnings (Default: None). target (Target): device backend target (Default: None). When this is supplied, several options are disabled: ``properties``, ``gate_lengths`` and ``gate_length_units`` are not used during the construction of gate errors. Default values are always used for ``warnings``. Returns: list: A list of tuples ``(label, qubits, QuantumError)``, for gates with non-zero quantum error terms, where `label` is the label of the noisy gate, `qubits` is the list of qubits for the gate. Raises: NoiseError: If invalid arguments are supplied. Nrz"warnings" argument has been deprecated as of qiskit-aer 0.12.0 and will be removed no earlier than 3 months from that release date.
