+	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.
