"""
This defines the properties common to all the IonQ devices.
Attributes:
fidelity(Dict[str, Dict[str, float]]): Average fidelity, the measured success
to perform operations of the given type.
timing(Dict[str, float]): The timing characteristics of the device. 1Q, 2Q, readout,
and reset are the operation times. T1 and T2 are decoherence times
errorMitigation (Optional[Dict[Type[ErrorMitigationScheme], ErrorMitigationProperties]]):
The error mitigation schemes supported by the device, where the key is the Python type
of the error mitigation scheme and the value contains the properties of the scheme.
Default: None.
