Main Question or Discussion Point

Hi,

I have a question with regard to the outcome of approximate quantum cloning:

For a general input state, it will always be entangled, right?
Let s = a|0> + b|1>

Then using say a Wootters-Zurek copying machine, we have:
|s>|Q> -> a|0>|0>|Q_0> + b|1>|1>|Q_1>

I need to perform some operations and measurements on the clones, but I need the states to be disentangled.
Is this possible? Any advice on how it should be done?

Thanks.
Nordin

It's not even possible to clone due to the no-cloning theorem.
