Return T1, T2 and frequency values from a devices BackendProperties.
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.infwill be used.
- Return type:
- Additional Information:
\(T_1\) and \(T_2\) values are returned in nanosecond (ns) units and frequency is returned in gigahertz (GHz) units if
valueis provided in
properties. Otherwise, the raw values (in unknown original units) are returned.
