# qiskit.providers.aer.noise.device.thermal_relaxation_values¶

thermal_relaxation_values(properties)[ソース]

Return T1, T2 and frequency values from a devices BackendProperties.

パラメータ

properties (BackendProperties) – device backend properties

A list of tuples (T1, T2, freq) for each qubit in the device. If $$T_1$$, $$T_2$$, or frequency cannot be found for qubit a value of Numpy.inf will be used.

list

$$T_1$$ and $$T_2$$ values are returned in microsecond (µs) units. Frequency is returned in gigahertz (GHz) units.
