thermal_relaxation_values¶
- thermal_relaxation_values(properties)[source]¶
Return T1, T2 and frequency values from a devices BackendProperties.
- Parameters
properties (BackendProperties) – device backend properties
- Returns
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 ofNumpy.infwill be used.- Return type
list
- Additional Information:
\(T_1\) and \(T_2\) values are returned in microsecond (µs) units. Frequency is returned in gigahertz (GHz) units.
