pygsti.error_generator

pygsti.error_generator(gate, target_gate)

Construct the error generator from a gate and its target.

Computes the value of the error generator given by errgen = log( inv(target_gate) * gate ), so that gate = target_gate * exp(errgen).

Parameters:
  • gate (ndarray) – The gate matrix
  • target_gate (ndarray) – The target gate matrix
Returns:

errgen – The error generator.

Return type:

ndarray
