+       IMPORTANT NOTE
+
+       (AB)^T = (A^T)(B^T)
+       
+       In quantum mechanics, if the relative state is S, then evolving
+       the relative state by a logic gate A requires computing AS.
+
+       This is inefficient as S is a column vector and it is more
+       efficient in terms of caching to use a row vector. Hence, the
+       simulator does not store S but only S^T. To apply the logic
+       gate A, it is not AS that needs to be computed but instead
+       (S^T)(A^T).
+
+       This means all the logic gates stored below are represented
+       as their transposed equivalents.
