My question: This includes also breaking or cracking the
primary key of the bitcoin wallet (Bitcoin Address)
?? :-(
Yes, on a theoretical quantum computer the private key to a public key can be computed much, much, much faster than on any traditional computer. This is true for ECDSA at least, which is the method used by bitcoin.
When quantum computing has advanced this far (will likely take some decades) and bitcoin is still around, the asymmetric encryption must be replaced by something that isn't susceptible to quantum algorithms. There are possible methods, but since it's all theory at this point research is still in its infancy.
