small_eigval_err_rate
(sigma, dataset, directGSTgatesets)¶ Compute per-gate error rate.
The per-gate error rate, extrapolated from the smallest eigvalue of the Direct GST estimate of the given gate string sigma.
Parameters: - sigma (GateString or tuple of gate labels) – The gate sequence that is used to estimate the error rate
- dataset (DataSet) – The dataset used obtain gate string frequencies
- directGSTgatesets (dictionary of GateSets) – A dictionary with keys = gate strings and values = GateSets.
Returns: the approximate per-gate error rate.
Return type: float
