qrisp.interface.Backend.error_rates

property Backend.error_rates

Error rates or calibration-related information for the backend.

This property is calibration-dependent: the values it exposes are only meaningful relative to a specific calibration run. Concrete backend implementations currently must include metadata that identifies which calibration snapshot the data refers to. For example, a timestamp, a calibration ID, or a version string. Returning bare error values without any calibration anchor is discouraged, as callers have no way to determine whether the data is current.

The format of the returned object is hardware (and vendor) specific.

Returns None if the backend does not expose error or calibration data.
