Fake Backend refresh() Method Not Working for Premium Backends (non-open) #2158

Description

@NavMohan-24

Describe the bug
I was working with Fake backends and attempted to update the noise model based on the latest calibration data using the refresh(service) method. However, my service instance is the open instance, and I am unable to refresh the noise model for backends that are not open-access.

Steps to reproduce

Image

  • Sheerbooke is available through open instance while Torino is not available

Expected behavior
The refresh(service) method should allow to fetching of the calibration data, as this data is already available directly through IQP.

Suggested Solution

If this is an intended restriction, it would be helpful to clarify it explicitly in the expected behaviour in the documentation.
