thermal_relaxation_values

thermal_relaxation_values(properties)

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 of Numpy.inf will be used.

Return type:

list

Additional Information:

\(T_1\) and \(T_2\) values are returned in nanosecond (ns) units and frequency is returned in gigahertz (GHz) units if unit for each value is provided in properties. Otherwise, the raw values (in unknown original units) are returned.
