I have a question with regard to the outcome of approximate quantum cloning: For a general state it will always be entangled, right? Let s = a0> + b1> Then using a WoottersZurek copying machine, we have: s>Q> > a0>0>Q_0> + b1>1>Q_1> I need to perform some operations and measurements on the clones, but I need the states to be disentangled. Any advice on how this should be done? Thanks. Nordin
