alpha_pauli(errorgen, tableau, pauli)#

First-order error generator sensitivity function for pauli expectations.

Parameters:

  • errorgen (LocalStimElementaryErrorgenLabel or LocalElementaryErrorgenLabel) – Error generator label for which to calculate sensitivity.

  • tableau (stim.Tableau) – Stim Tableau corresponding to the stabilizer state to calculate the sensitivity for.

  • pauli (stim.PauliString) – Pauli to calculate the sensitivity for.

Returns:

Linear sensitivity of the expectation value of the desired pauli observable to the specified elementary error generator for the given stabilizer state.

Return type:

float
