Abstract
It is believed that superselection rules in quantum mechanics can restrict the possible operation on a qbit. If this was true, the model used by Mayers for the impossibility of bit commitment and by Kitaev for the impossibility of coin flipping would be inadequate. We explain why this is not the case. We show that a charge superselection rule implies no restriction on the operations that can be executed on any individual qbit.
