build_identity_vec
(stateSpaceDims, basis='gm')¶ Build a the identity vector for a given space and basis.
Parameters: - stateSpaceDims (list of ints) – Dimenstions specifying the structure of the density-matrix space. Elements correspond to block dimensions of an allowed density matrix in the standard basis, and the density-matrix space is the direct sum of linear spaces of dimension block-dimension^2.
- basis ({‘gm’,’pp’,’std’}, optional) – the basis of the returned vector. ‘std’ == Standard (matrix units) ‘gm’ == Gell-Mann ‘pp’ == Pauli-product
Returns: The identity vector in the desired basis.
Return type: numpy array
