  We define the disentangling power of a unitary operator in a similar way as
the entangling power defined by Zanardi, Zalka and Faoro [PRA, 62, 030301]. A
general formula is derived and it is shown that both quantities are directly
proportional. All results concerning the entangling power can simply be
translated into similar statements for the disentangling power. In particular,
the disentangling power is maximal for certain permutations derived from
orthogonal latin squares. These permutations can therefore be interpreted as
those that distort entanglement in a maximal way.
