          .. note::
  
              The matrix elements along each axis are ordered by bitstring. For two qubits the order
              is ``00, 01, 10, 11``, where the the bits **are ordered in reverse** by the qubit index,
              i.e., for qubits 0 and 1 the bitstring ``01`` indicates that qubit 0 is in the state 1.
              See also :ref:`the related documentation section in the QVM Overview <basis-ordering>`.
