pygsti.std_to_gm

pygsti.std_to_gm(mxInStdBasis, dimOrBlockDims=None)

Convert a gate matrix in the Standard basis of a density matrix space to the Gell-Mann basis (of the same space).

Parameters:
  • mxInStdBasis (numpy array) – The gate matrix, (a 2D square array)
  • dimOrBlockDims (int or list of ints, optional) – Structure of the density-matrix space. If None, then assume mxInStdBasis operates on a single-block density matrix space, i.e. on K x K density matrices with K == sqrt( mxInStdBasis.shape[0] ).
Returns:

The given gate matrix converted to the Gell-Mann basis. Array size is the same as mxInStdBasis.

Return type:

numpy array
